COVID-19 travel policy amendment, effective today.

Update to COVID-19 policy amendment, as drafted by the staff and
vetted with the Board of Directors.

Formatting / typo fix: spelling error.

Spelling error is corrected. Does not change policy.

Minor grammar fix: "that period" => "hiatus period"

Intent was clearly for the hiatus period here, but use of "that" might be
confusing, particularly to non-native-English readers.

Formatting change: no policy change: number wrong.

Correct a number for the list; this is a formatting/typo change only and no
policy change here.

Formatting fix only: proper bullet list.

The HTML converter thought this was quoted for monospace font because I had
it indented too far. This commit is a formatting change only; no policy
change.

COVID-19 Travel Reimbursement Policy as approved by Directors

This COVID-19 travel policy amendment is temporary but in effect indefinitely
until revoked by Conservancy's Board of Directors. This policy was enacted
by the Board of Directors as of today.

Remove old paragraph that contradicts policy.

This summary paragraph is old from the time before we switched to using M&IE
to cover currency. I'm unilaterally removing this paragraph because it quite
clearly conflicts with the other statements in the policy that are newer.

Travel Policy: Brazil payment instructions: fix typo.

<mauriciofauth> It reads as follows: Brazil: IABN;
<mauriciofauth> But I think it should be: Brazil: IBAN;

Visa Fees: reimbursement is permitted.

Historically, we have always allowed visa fees, as described herein, for
reimbursement. Technically speaking, they were prohibited because of this
text early in the policy:
"only those categories of expenses listed in this document qualify."

I've left that text in place and added visa fees explicitly.

Travel: Update link for PayPal's currency list.

RT#407.

Travel: Use GFM markup for the flight time/budget table.

This looks a little less good in ASCII, but lets us automate conversion to
HTML.

Travel: More expensive flights that provide comparable time savings are in-Policy.

The current "lowest fare + $100" rule is simple, but provides less and less
choice as distances get longer. The most common feedback we hear about the
travel policy is a wish to have more flexibility to choose shorter flights.
This provides that flexibility by allowing more expensive flights that
provide time savings, while keeping the rules relatively simple.

Travel: Allow specific expenses to be approved by any officer of Conservancy.

It can be difficult for the Executive Director to approve expenses in a
timely manner if they themselves are traveling or taking time off. Allowing
any officer to approve the expenses helps us be more responsive with minimal
additional risk.

Travel: Add $150 to the limit on int'l airfare without preapproval.

The limit has been $1,500 since the first commit of the policy in 2012.
Inflation and other economic forces have brought us to the point that
international travelers routinely show us searches where the cheapest fare
is around or over $1,400. Increase the limit to try to level the number of
flights requiring preapproval.

Travel: The 90-day limit for expense reports is from the last day of travel.

This was always our intention. However, the previous wording didn't account
for gaps in the time that advance purchases (especially flights and other
long haul travel) are made and the time the travel actually occurs. This
updates the wording to match our intention.

Travel: Remove redundant sentence.

This is covered in the previous sentence, with "teh costs the Traveler
incurs are lower than this rate."

Travel: Move Additional Travel section up.

This puts it closer to the policies about booking transportation, where
readers are most likely to want it.

Travel: Remove note that requests are handled once per week.

This is still sort of our default handling, but things can move in both
directions depending on what else is going on. Just strike it.

Travel: Update information about rates we use.

* Introduce a "Rates" section that's referred to throughout.
* Explain how the total M&IE allowance is calculated.
* Update the info about currency conversions to explain we now use Open
Exchange Rates based on the date of the reimbursement request.

Travel: Reformat the policy as Markdown.

This should be more accessible than the previous asciidoc.
