Make additional bar when time left with donation exceeding goal

This is a first draft of making another bar appear after the
completed "matched!" bar that will show how much extra we've gotten
beyond the match amount.

Add holiday card to banner at top for next few days

Also, fix a few URLs .

progress bar: Remove display-table vertical align workaround.

Was causing some display glitches on some browsers. Using nested flexbox instead.

progress bar: Drop JS, make mobile friendly, match design to new site.

The existing jQuery UI-based fundraising progress bar used a float layout,
making it hard to adapt for mobile use. Given that there is not interactivity,
I've dropped all the JS and switched to a flexbox layout. This works well
because the bar will stretch to fit the text rather than always maintaining its scale.

Repair menu highlighting, both for main menu and submenus

During the recent improvements made on the website, the menus and
submenu highlighting for selected menus fell into disarray.
Correction requires changes to the CSS and templates both, because
Django doesn't really have a convenient way to set variables in
templates to use to solve this.

There are still a few submenu items highlighting not working even
after this commit. More work needs to be done.

Apply max widths and margins to all pages.

Due to the varying types of layouts used and the short time-frame the best
option seems to set a max-width etc. around the "outercontent" block. For now
this means we can't do "full bleed" body content, but that's not currently used
anyway.

Rename "supporter" to "sustainer" in templates and URLs.

Does not rename the models.

Switch to SVG logo.

Will look better on mobile.

First-pass implementation of new design for home page.

Uses a combination of CSS changes and Tachyons classes to implement the design.

Adds the non-minified Tachyons CSS library itself and SVG icons from Font Awesome.

templates: Finer-grained split of fundraiser header display.

Always show the header if a fundraising goal is active.
Only show the progressbar if there's money in it.

base: Take down fundraiser progressbar.

Per Karen in e-mail.

base_conservancy: Don't show the progressbar until a fundraiser is ready to go.

This lets me push this now without visible effects until the data is ready. ;)

base: Start progressbar for new match.

This code should be easier to adapt to future matches too, by just changing
the constants in the first `with` declaration and whatever text is desired.

css: Start a separate stylesheet for "big screen" styles.

I'm about to add more and I *suspect* this will be easier to maintain
in the long term, rather than duplicating the conditional many times.

Reorder topnav buttons.

This better matches what I see on other NPO sites.

Karen asked for this change.

Rename Members->Projects in menu navigation et al

Due to confusion about "members" and "supporters", we want at least the
menu navigation to not use the phrase "members" since some Supporters
expect that to refer to a type of donor.

While we will not be rebranding "member projects" fully at this time, we
want to favor the term projects.

A few additional changes, in particular moving files from members/ ->
projects/ directory will be needed in next commit.
