Add tile bounds option to limit tile loading to a given region
Documentation to reflect changes made in pull request #1028. Added additional properties to the LocationEvent.
Allow pointer-events to be set via options passed to shape
fixed bug where wms tilesize option was ignored when setting
 wms params width and height
Rename TileLayer.options.tileBounds to bounds
Better parameter handling for TileLayer bounds
Use proper factory call for bounds option
store the event listeners using a hash if the context have a leaflet_id.

When removing a layer,the slowest part was to remove the event from the map.  For each event, the removeEventListener method had to loop the whole list.  With thousand of layers, it become very slow to do.  With a hash used has an index to find event listeners for a given leaflet id, its no more an issue.
Path CANVAS adds a click event if clickable but do not clear it on remove.  This adds the necessary remove listener.
use a property for index length because its slow to get the first property or get the length of a hash.

Fixes #1041, Android WebView triggers two clicks at once. This calls
L.DomEvent.stop(event) on the second if two clicks are triggered within 400ms
of each other. Double click is unaffected however.

There are other workarounds that focus on _fireMouseEvent(), however I had to
resolve it at the click event level as my map, markers, controls, were all
affected.
This makes sure we only do the Android duplicate click workaround on Android
This modifies the Android WebView phantom click workaround.
Previously it was blocking when an element had multiple click listeners
because those events were fired rapidly. Since Android fires its second
click at approximately 300ms after the first we do a check to make sure
that at least 100ms has elapsed but not more than 400ms.

TileLayer.Canvas.redraw() now returns this.
