Initial work to make the project build with gradle.
Things seem to be working.
Trying to get the Delete all with undo functionality to work. The about box is broken, and no idea why. Gradle is a pain.
Ignoring workspace.
Fixed build.
Committing subproject pointer.
Reformat code, and added line to refresh timers when a clear all is undone.
Metadata files.
Updated notices, and extracted a string.
Added signing configuration.
Updated version number to 0.6
Ignoring .gradle changes.
Merge branch 'release/0.6'
