Fix to ava avatar issue
Minor changes

Should do the following:
Adds a tooltip for retreating
Adjusts range for display and tooltip of vanguard cannon
Minor edits to descriptions of limited range abilities to reflect hexes
instead of squares.
Battleship Adjustment for M15

Changes it to have the full effect of disable, removing flak and shield
generation from the battleships,

Hopefully, anyway.
Stupid mistakes

Fixes a few dumb errors I made, like leaving out a parenthesis.
