REGISTRAR,GUI: new form item "auto-send button"
WUI: initial wui commit (work in progress)
WUI: fixes
WUI: added empty gwt project for perun-wui-cabinet

- Added base config files for new wui webapp for cabinet.
- Added images and js sources.

WUI: support for GWT's super dev mode

- support super dev mode of GWT
- any script loading in gwt.xml must be placed in code
  into method onModuleLoad() and loaded by ScriptInjector
WUI: new way of loading CSS

- Do not insert CSS in HTML page but use new class
  PerunWuiCss which extends ClientBundle. This will make sure,
  CSS is part of native clean.css file bundled with GUI.
- Load CSS in each module like: PerunWuiCss.INSTNACE.css().ensureInjected();

- Next future stage should be associating CSS directly with widgets, so it's
  loaded everytime widget is used and not manully in onModuleLoad().
WUI: imported changes from main GUI
WUI: support for devel and production profiles

- Each WUI application now has two modules (profiles in maven)
- Production module is base in gwt.xml means but must be set
  in maven as -Pproduction profile.
- Devel module extends production and sets some debug config
  but is default in maven builds.
- Added PerunWebGui.properties for production

Note: on some IDEs for WUI devel builds you must exclude production
resources folder to get devel like configuration. Maven itself
works correctly.

WUI: support for multiple authz

- Added new html pages with authz definition property, so
  Apache can enforce proper way of authorization and WUI
  knows URL, where to search for Perun instance.
