New feature: notes page
Added a notes page activity where notes, partial solutions, and anagrams can be experimented with. I find this useful for cryptic crosswords.
This includes the addition of a NotesActivity class as well as a BoardEditText widget (akin to TextEdit) to edit text in crossword style. I have also added an options menu to the clues list activity, though the only option is to get to the notes page.
Notes are stored in the same file as the user's crossword answers in a section marked with ANTS and DNTS (across/down notes). This is similar to GEXT and if it is not present it is assumed empty. (Ie existing files with previous versions of Shortyz should work perfectly well.)
A smaller technical change is to the PlayboardRenderer class's drawBox method to take the selected square position (used by BoardEditText).
Future work might be to refactor NotesActivity and ClueListActivity to remove a lot of copy-pasted code to do with keyboard handling.
edit: i made an issue earlier asking if i should do this, but i had time today anyway.
editedit: this version still needs longer term testing. Basic features work fine.
Inspired by issue #124 i've added a preference to display the scratch part of the notes page on the playboard in smaller letters. As per the commit message, this turned out to be more awkward than anticipated and needed a lot of new code, which may or may not be the best approach. Comments welcome.
Feel free to accept without this commit (f31bee9).
edit: just spotted a small bug, working on it now.
Bug fixed -- this affects all versions, so commit 7fb08c9 should be applied with anything from this PR.
Apologies for the increasingly complex PR!
