Adirelle:
	- Hopefully fixed ticket #73.
	- Revamped the search widget.
	- More work on the graphical configuration of the manual filter.
	- Overhauled the "Manual Filter" configuration options ; fix ticket #88 and #90.
	- Fixed the internal name of the "Filter Override" module (and fetch the associated settings).
	- Don't choke on items not in cache; should fix ticket #86.
	- Hopefully fixed ticket #84 (wrong button placement at startup).
