0.9.2

Release addressing some issues on the issue tracker before a push to AUR.

• Add progress block, which displays progress when a hint with the name "value" is present (#4).
• Fixed a bug with certain window managers where wired would steal focus (#7).
• Added notification_actionx_and_close shortcuts (#10 #9). (thanks @LordMZTE)
• Added backtrack_scroll_pos option to ScrollingTextBlock, which will try to maintain scroll position when a notification is replaced.
