more build tweaks
- make update URLS https - required by firefox+greasemonkey
- add build name + date/time to description of all plugins, and moved to front for main IITC
- ensure all plugins have a A.B.C. version number format - required now they append the date+time digits
- no smooth upgrade path from current 'dist' folder - so changed to 'release'. users will have to manually update this time, but will be fine fron now onwards (in theory!)
