This commit should have no functional affect. It just changes the
abstraction level of OpenLayers from completely abstracting away
getMapExtent etc, to using OpenLayers's functionality directly but
providing proj and unproj to make projections palatable.
Where a translatable string contains (directly or indirectly via
interpolations) some HTML it is better to add an _html suffix to
the key rather than wrap the result in raw so that escaping is
handled automatically for interpolations.
It's not worth doing until a string is changed and needs to be
retranslated though, as it will just break translations.
This edits the front page copy to be more direct, link off to more
useful resources, and guide people to register for an account. It
also moves partner links to below the donate link.
Restructure the links section in the sidebar to split it into two
major groups, help and community and move the diary link from a tab
to the community section of the sidebar.
Uses the parent of the tabnav element to do its positioning, and fixes
this style in RTL and small.
Also move the greetings block into the top-bar div in order to cleanly
have it share a border with tabs.
Moves action buttons to be with the form instead of way over on
the opposite side of the page.
Reorganizes "remember me" to a more typical spot on the page.
Get rid of separate "create account" panel and replace it with an
above the fold link.
Make sure all strings are translatable; replace a manually constructed
link with link_to; improve date formatting; and use cycle to alternate
colours for the table rows.
The expiry is passed directly to memcache, which treats any value
over 30 days as an absolute time, so using 1 month leads to sessions
expiring as soon as they are created.
