Plugin for Synwrite. 
Adds commands to increment/decrement of number under caret. Numbers in 
css/html supported: 100px, 1.200em. Floats supported (dot must be used).
Multi-carets supported: all numbers for all carets affected.

To set hotkeys for increment/decrement, see Synwrite FAQ, how to do it.
HTML color tokens not supported yet. It's untrivial.
