New compressed versions of some JavaScript files, bringing them up to date with recent changes.
Fixes for issue # 50
These static import scripts weren't setting BASEPATH before attempting to load config files.
CMS pages (page.js) were using ../../.. as the relative URI to the /ajax endpoint,
this has been changed to ../../../.. and now works.
Template for click-querying a trail piece, was displaying the GID of the trail piece.
This debugging info doesn't need to be visible to the public, so was placed inside <!----> comments, where it's visible via View Source.
Major upgrade and UI fixes:

- Leaflet upgraded from 0.3 to 0.7.1, which means no more scalebar library, Wicket for WKT parsing instead of old custom library, and numerous small internal fixes to common.js, constants.js, mobile.js, and desktop.js

- Minor UI changes per list: removed Pavement selectors from Directions, removed Fastest Route from directions, true text input for Share (mobile) instead of text DIV hack for old iOS, added Directions link in POI query popups.

- ajax.php: non-Published Loops no longer appear in text search results.
Minor CSS changes as prep work: Elevation profile images all have .elevationprofileimage CSS class.
Mobile "Share" facility now has explicit Share on Facebook and Share on Twitter hyperlinks, with logos and all. This is intended as a workaround for older iOS devices who cannot copy and paste reliably from text onputs, but will be egneerally welcome even on more functional devices.
Mobile: minor change to share facebook and share twitter buttons. Added some padding and spacing.
