hiding crop media from ofr branch
short mod to tutorial

testing the new deployment from mp-ofr repo...
removing (hiding for now) crop specific media
removing links from page guide tours
allowing url to specify sublayer as well as layer to auto-activate

visualize/#layer-name-slug now works for sublayers as well as top layers
updating Layer model and visualize view to work with updates to other mp projects

(added filterable field to Layer model and default value for
default_hash in visualize view)
updating OpenLayers imports in arcrest_example template

(release of OL3 seems to coincide with removal of OL dev stuff from
github - OL2 example, etc...)
Merge branch 'actual' into ofr
removing initial_data fixture from data manager
adding migration script for filterable layer field
adding pinch zoom for windows mobile devices
adding TouchNavigation and PinchZoom controls

I had thought these were already included by default, but I witnessed
pinch controls not working on iPhone5 today…after receiving reports of
touch controls not working on OFR with Microsoft Surface Tablets
fixing SimpleLayerSwitcher references

so that the references refer to the class rather than the id, after
seeing the id change from SimpleLayerSwitcher_28 to
SimpleLayerSwitcher_30
Merge branch 'actual' into ofr
commenting the windows pinch zoom addition
adding WindowsPinchZoom import to mobile map
moving OpenLayersWindowsPinchZoom source file
adding pinch zoom import to mobile map template
adding a touch action prevention from map element in IE

which will hopefully allow the OpenLayersWindowsTouch event to fire
adjusting SimpleLayerSwitcher slightly

so that mouse up events can be handled in MP (solving the problem for
iPad/touch viewers in which the simple layer switcher would remain on
screen because there was no mouse leave event to close it)
