Feature/local metadata more tags (#832)

* Stashing code

* removed some debug code on series detail page. Now detail is collapsed by default.

* Added AgeRating

* Fixed a crash when NetVips tries to write a cover file and cover directory is not existing.

* When a card is selected for bulk actions, show an outline in addition to select box

* Added AgeRating into the metadata parsing. Added a hack where ComicInfo uses Number in ComicInfo rather than Volume. This is to test out the effects on users libraries.

* Added AgeRating and ReleaseDate to the metadata implelentation.
