New attempt at text selection.

First working version of highlights.

Still very basic, you can set a highlight and it will be there
as long as the app runs.
No longer crashes on page number calculation.
Added Wiktionary lookup
Book-specific settings are now saved in a seperate config file.
Can now create highlights, and they change colour on click.
Can now delete and re-colour highlights.
Added basic note support.
Some UI changes to note editing.
Highlights are properly stored now.
Slightly nicer menu.
Added dialog for highlights.
Added "share" function.
Text selection now closes on back button.
Hide actionbar on back-button (if applicable)
Nicer display of progress, including pages.
