 Widget groups are here!

Thanks to HalcyonD we have widget grouping. All core widgets go to the group Core. If a plugin introduces several widgets,  they go to the separate group. All single widget plugins go to the group Other.

• Fixed allowOrder setting in GRID (c0ee18)
• Fixed GRID checkboxes field update if no checkboxes are set
• ipSendEmail now supports also a string as a file to be attached to the email

• fixed Bootstrap's modal backdrop height calculation
• fixed Bootstrap's double modal scroll issues
• gallery widget management in popup
