Fixed issue #85
Added (very limited) Keyboard shortcuts, they’ll be expanded later on
Changed build SDK version to Lollipop
Added option to show user’s hostmasks again
Changed Buffer indicator colors
Fixed the Clickable ActionBar Title
Does not show a topic Dialog in queries anymore
Added ability to edit channel topic
Moved the icons into the mipmap folder to make them less blurry in launchers
Usually launchers show the xxhdpi icon on xhdpi devices, but only if the icon is specified via the mipmap folder
