Forced a redraw after creating a touchimage (and thereforce cloning an image node) by hiding then unhiding the imageRoot
Images now scale to the space available when created
Images are positioned and angled a bit randomly
Trying various things to persuade chrome to redraw
Changing the z-index of the first touchable div in the list makes new things be drawn
Setting the zIndex then changing it again after a short timeout makes things appear properly
Merge branch 'dev-menu' into dev
Made some gradients to use as mask images
Staretd work on zOrdering for the TouchImages
Added a method to the manager to bring a specified touch image to the top
TouchImages are now moved to the top when touched
zIndex is now twiddled on TouchImage creation to force a redraw
Made tapping on TouchImages bring them to the front
Locking a TouchImage does not lock the zIndex
Merge branch 'dev-zOrder' into dev
Merge branch 'master' into dev
Merge branch 'dev' into dev-menu
Updated the plan a bit
Added another menu button to stretch the menu a bit
Added a method to calculate the required size of the menu_container div
Fixed tapping a Image to only bring it to the front if tapping the image and not the buttons
This means closing will not bring it to the front (and cause it to not be deleted)
Also means locking will not bring to the front
Also made zTwiddleing of the first image happen on the new images load event
Merge branch 'dev-menu' into dev-menu-sexyMenu

Conflicts:
	src/menu_buttons.js
The menu buttons can be dragged left and right without restrictions
Added some basic limiting of horizontal scrolling
