renaming removeFrom to remove 

This change renames the 'removeFrom' function to 'remove' keeping this plugin inline with the standard leaflet control. 
See here for information on when leaflet changed their controls removal function from `removeFrom` to just `remove`: https://github.com/Leaflet/Leaflet/commit/eec19a441bc56e2c6db0dedc1719932464523cf0
