Added category for commitments to docs, and then removed a debug
Fixed lingering merging issue with category commitments in saving
Fixed event saving bug
READ FULL MESSAGE! Implemented de-selecting all events and filtering
commitments by category

Since commitments that were on the database before categories in
commitments were implemented do not contain a category, they create
trouble with this. As a result, please delete database before merging
this.

Will make UI of side bar panel prettier.
Finished implementation of commitment filtering by category.

Improved UI, created top level events and commitments filter which are
independent of category filter.
