sketchPatch
getting git to ignore the usual hidden files that no-one cares about
trying to consolidate the "shadow" into the CSS puzzle

to compensate.
adding the separate FA thumbnails stripe to the front page

so now in theory the front page should be OK.
fixes to links, and to an occurrence of "Samiate"
1) put the contents of the test page in the first page 2) eliminated all old and unused images (they are still in the repository history anyways)
renamed FA_Alex_May into FS_AlexMay…

…so that the naming is consistent with the other pages
moving the featured sketches pages in their own directory
fixing the links to the sketches of the 17 CoLa-I groups

they weren't working because the %20s in the links were jamming things
up
the thumbnails of the sketches in Alex May's page now link to the proper sketches

… to make it consistent to the other FS pages
now Ricardo's thumbnails link to the proper sketches

...to make it consistent to the other FS pages
renaming the page of Samiat to make it consistent with the other names
renaming Ricardo's page to make it consistent with the other FS pages' names
renaming Slub's page to make it consistent with the other names

removing reference to Page2.html from yaml file as there is no such page
removing IE.css as it's not used anywhere. Probably a leftover from an old test.

this was only a test, we never used it
removed admin pages apart from the main one…

these are legacy pages from CPedia and are not needed in sketchPatch.
removing the demo directory of jquery-tooltip
