Add map.js with m_import to parse input

m_import(string input) parses 'input' & puts it in global m (2d array)
m[y][x] or m.byXY(x, y) return 0 for non-walkable tile, 1 for walkable
m_print() prints the map to console (with 0s and 1s)
Add sanity checks to request.js & whitespace
Merge remote-tracking branch 'origin/master'
