logged-in users data access

[kdarras]

After login, a link to the user-accessible data, named "my sounds" should appear in the upper menu. The link should be prominent, with a different background color (whatever looks nice).

Only projects with accessible collections should be listed there, and projects with public collections should be separated (lower priority).

For consistency, inside the user privileges window, grayed out, inactive but checked checkboxes should be shown next to the collections that are public, as well as in the "view" column for those that have public tags.

The admin interface link should be renamed to "dashboard"

Accessing an empty project (without collection) throws an error:

adjustment needed:

I have a normal user that has access to the public demo collection recordings and its public tags:

The user privileges window needs to show the gray, checked box under "access" (as he will always have access to this public collection), otherwise it is not clear what this box stands for. Similarly, since the tags are public too, there should be a gray, static checkbox under "View".
Ideally, on mouseover, the checkboxes would display "This collection is public" or "These collections' tags are public".
