letters working
fixed solver letter, symbol, !color
nothing
fix MAJOR bug removing values, hint methods

Fixed but that on fist xbox click binded that and only that cell to
updating of user board, so clicking x would remove that cell display but
the REAL board was only updating on that cell...this should fix a few of
those "phantom" bugs that only happen sometimes :)
checker now highlights ALL errors and Empty cells
removed unused debug button from index
checking column and row for single value missing
box check done, hint now validates board before hint
worked on infesticating cells, came up with better way

I will try and work on it tomorrow early so we can get a good demo
going, if not we still have a semi working help feature
Merged with help

Hopefully everything still works
