Switch from the shortcut.js to the jquery.hotkeys.js library.

The original shortcut.js library has trouble handling special keys.
For example, if a shortcut for 't' is defined, pressing F5 will
trigger it because the keycode for F5 is equal to the charcode for
't' (116).

PostgreSQL support (initial revision)

This adds support for PostgreSQL as a database for selfoss. Tested with
pg 9.0, but anything reasonably modern (8.x+) should work.  Testing
platform is debian stable on i386 with pg 9.0.7 and php 5.3.3-7.
