WIP: Processes tags
This merge includes:
- AccountService dependency added.
- User entity added to hold processes' users specific data.
- Back-end logic to link processes with users.
- UI for displaying tags.
Further to do:
- Resolve the issue with "unavailable" tags - for some reason, UserManager is not available at start of the app start for a short period. This makes it impossible to link processes with users. I will investigate it further.
- Probably some admin/normal user check (however, is it necessary?).
- Clean-up of the code (use of get_user function, tag css classes, naming).
