Fix inexplicable stacking of ToolbarIcons caused by width of 25.999 (instead of 26) being coerced to 25 by parseInt.
Install local version of leaflet-draw to test modified version (see manleyjster/Leaflet.draw#toolbar-handler for the modified version).
Add child actions from ToolbarIcon.
Revert to earlier API - toolbars receive an array of toolbar actions (function which return a handler) as their first argument. Assume that each handler inherits from L.ToolbarHandler. Modify tests and examples to reflect new API.
