WUI: added base cell styles for PerunDataGrid
WUI: proper static resource handling

- We use resource gwt module to load non-html static resources
  like images and CSS files. This way we can skip call of ensureInjected()
  in every module. Also images can be in one (base) module and
  not in every module webapp folder.

- Split CSS files for core and admin app.
WUI: updated form design

- Validate also non editable form items.
- Display red asterisk for required form items.

- When multiple emails are provided by IDP, then allow
  user to select one of them or provide custom.
- Show warning, when not verified email is provided by user.

- better translations
- backported change with link to consolidator
- added page with submitted apps
- translatable tables
- localization is now part of session
- better display of cert names
WUI: Unified API caller

- Dropped cross-site request support for local development.
- Use unified JsonClient which returns Request to be
  canceled or checked if is pending.
- Removed jsonTimeout property from configuration, since new
  GET requests last as long Apachee allows.
WUI: Allow to set correctly GWT and mvn:gwt plugin versions

- We now have same GWT and mvn:gwt plugin version across whole project.
- Each module can override it in properties tag in pom.xml.

- Show modal dialog when similar users were found with selection
  of identity to join into (cert or IDP).

- Fixed style for PASSWORD input field.
WUI: radio for registrar
