Fixes for Fork CMS 3.7 & 3.8

Additional fixes for Fork CMS 3.7 & 3.8. Some file/folder/paths renaming to camelcased structure.

Oh and the blog module still uses a lowercase ("Files/blog") folder in the frontend files folder, instead of the "Files/Blog" folder. I fixed that. However, the profiles module uses a capitalized folder ("Files/Profiles") but all subfolders are lowercase ("Files/Profiles/avatars").
