Changes, see comment

Removed redundant pheno_functions.js
- JSONified all the cookies settingand retrieval in the PHP backend
(before it was using array_values() :( )
- added HTML GET cookie/config setting. so that URLs can be used to link
a player
- added a copy link button that generates a URL for the layout &
timestreams (need a .getCurrentTime() from timegraph.swf to scroll to
the current time/frame).
- trimmed some whitespace
- fixed timespan_days parsing in the generator
