Albert v0.11.2 released

This release contains the latest fixes. Further the following minor things changed:

• The web searches can not be enabled/disabled anymore as fallbacks. There will be a more generic mechanism that is responsible for that.
• URLs starting with http and https skip the TLD validation. This way you can access e.g. host in the LAN.
• The files extension does not require at least three chars anymore. Make sure you set your file filters correctly.
• Home and End now work for the results list holding Ctrl.

Check the git log for details.
