expanded board

expand the board to 11x18 and calculate tile location based on
column/row
add water tiles
Roman city overlay

preliminary
fundamentals

refactor code for future redundant additions, add city overlays to board
start adding units

just a soldier, temporary text-based graphics, no unit stats
try to move sprite on key press

not successful at this time...
Update README.md
move sprite, but can't control it

Phaser's documentation (and the developers' writings) are all wrong. You
don't redraw a sprite at a new position with "sprite.x = x", it's
"sprite.body.x = x". sprite moves with game.physics.moveTo(), but it
moves in the wrong direction starting with the second call. So much more
work to be done...
more work on moving sprite

Sprite moves only in x direction to infinity...
coordinate systems of unit.x/y and unit.body.x/y must have different
origin points... further research required
Update README.md

Add links to where I can grab some graphics and audio
move active unit to neighboring tile
Don't move into water

Add function to check if this is a legal move, prevent units from moving
into :ocean: water
limit unit moves

and set default starting health
Merge branch 'master' into gh-pages
