Fixed the bug with continue black where it would not work for a single tile connecting two black regions. However, there are still some problems with adding multiple black tiles under the continue black rule at once, mostly where it allows a tile to be added where it should not be added.
Updated more treetent icons

aroundTent, contra_adjacentTents, noTreesAround

Finished updating nurikabe rules

rules updated: OneUnknownRegion, RuleWhite, SurroundBlack
contradictions updated: MultipleNumbers
Implemented the PuzzleModule methods {getAbsoluteNextCellValue, getNextCellValue, getStateName, getStateNumber, numAcceptableStates} in terms of two new methods intended to be made abstract {getCellNames, getUnselectableCells}.
Updated puzzles to use the new getCellNames and getUnselectableCells mechanism.
Added flags to the ant script to make line numbers actually appear in exception stacktraces.
Renamed "New" and "Open"

Now "Open Puzzle" and "Open Proof"
Changed "New Puzzle" to "Open Puzzle" in the menu (Aaron's change only affected the buttons).
Updated the Fill In Black Rule

Should work for regions that are partially filled with black cells
Removed duplicate rule for nurikabe
Create ContradictionIsolatedBlack.java
I did something wrong with git pull, pushing my local branch (which is up to date) to see if i can fix it
Merge branch 'master' into NurikabeTest
