Clean up Mainwindow for adding plugins
Add ThemeManager to Main window and pass to plugins
Add event Manager code to plugins and define some listners
Update AlertDialog to send message and allow text to be entered
Found some device dependent problems in the tests of the theme
rendering (when monitor resolution changes, so does font size (in
pixels)). This meant that the tests failed (as they are comparisons
with golden-bitmaps). Have updated the tests to do a more "approximate
comparison", with a low tolerance. This is slow currently, could do
with optimising.
