Widgets inside folders, and widgets changes

0.8.97
Added: Finally, you'll be able to add widgets inside folders!

Changed: Due to confusion among some users, we decided to change how the widgets are resized and aligned. From now on, the widgets will no longer be freely resized (vertical and horizontal) – the only way to resize is vertically, but you'll be able to set the alignment through the widget's settings. Also, we removed the widget's background and stroke options from the settings, for now.

Other fixes and improvements.
