Misc Bugfixes (#1015)

* Fixed some security issues in dev env

* When deleting folders in bookmark cleanup, delete empty folders correctly.

* When a new library is created and cards are added, cards can have a blank library name. Card library name code is reworked to be much lighter on memory.

* Added a config for github issues to disable blank issues.

* Skip any sort of directory iteration code if we haven't deleted any bookmarks.

* Fixed a bug where some style overrides were duplicating. Now logic is much more targetted, only applying to the correct tags.

* Applied sorting to the filtering apis.

* Reverted one of my changes for a better version Robbie did.
