Remove CV skills, bug fixes I'm an idiot. Ignore the half implementation of some insane one by one deletion in details. Isntead I used a similar solution to the checkboxes for skills having tags. Also i found and fixed a bug where removing all tags from a skill threw an error. Also the modelstate.isvalid stuff is being used wrongly i think, but not in a way that's breaking anything soo.
