* Allow sorting by months for depreciation list view
* Added dataTableLayout to standardize the list display table
* Implement the dataTableLayout() on the list view blade
* Split the view into tabs so we can combine asset depreciations and license depreciations
* Updated depreciation view to use tabbed interface for assets and licenses
* Added asset models to depreciation details page
* Make asset model category sortable
* Added cateory as allowed to be sorted on
* Added category sort scope
* Removed offset variable
* Small fixes to asset modes display in depreciation to bulk edit models
* Cleanup model bulk-edit
Use the general partials where appropriate, as well as display a list of
what models we are editing in the bulk edit.
* Use new api based fetch/display for modal select2.
This is just copy/pasting the code currently because I'm not entirely
sure how the two pieces of code interact.
* Remove old helper functions that are no longer necessary with our populating of select2 dropdowns via ajax.
