Prefix localStorage variables with "ziften"

Since we share the localstorage with Sifter we should prevent possible naming collisions
Also update/read the projectlist on the main project page

This resolves issue #10
Use jQuery UI styles from Sifter

Fixes issue #9

- Use the "mentions" autocomplete style
- Suppress the jQuey UI accessability message
- Remove the jQuery UI CSS and image as we use Sifters CSS and images now
- Strip CSS and images from Chrome web_accessible_resources
- Modified jQuery UI JS so that it applies the "ui-state-hover" on focussing/hovering over an element instead of "ui-state-focus" so Sifter styles will apply correctly.
Count the number of issues in the custom "others" section
"Others" is now also grayed out when 0 results in set
No results in projects autocompleted showed "null"
Bumped version numbers of Chrome and Safari to 1.0.1

also changed safari build ID to another format to prevent strange behavior.
Merge branch 'refs/heads/development'
