editing.

[BUGFIX] Fix loading of registry entries for namespace

When calling get(), all entries for the given namespace are loaded only
if no value for this namespace has been set() before in the same run.

This patch fix this by tracking the loading of namespaces and check the
state before set() or get() is processed. In case the namespace was not
loaded before, the loadEntriesByNamespace() is called to prevent
overwrite of values.

[TASK] Move backend module icons to respective location

In TYPO3 CMS world each extension contains multiple icons:

+ "extension icons" (ext_icon.gif) to identify the whole extension (EM/TER)
+ "module icon" as Start button per backend module (module menu)
+ "record icons" in recordlist as clickmenu link
+ "action icons" like save, close or info (toolbar)

Currently all icons look the same in the backend (16x16 pixels, same theme).
Also many icon files are used multiple ways (e.g. ext_icon.gif as module icon).

In order to be able to differentiate icons better by their primary function
this patch introduces a common folder as defined location for backend
module icon files and demontrastes a naming schema "module-name.xxx".

Also this patch reduces cohesion and coupling of backend extensions since
extensions now bring their own icons in a predictable fashion.

This supports alternative backends that do not rely on t3skin at all.

[BUGFIX] Remove PHP warnings when no icon is found in FormEngine

If running in development mode and an icon
in FormEngine is not found, TYPO3 shows
the PHP E_WARNING of getimagesize() in a flash message.

The check should therefore be done in a cleaner way,
without the @ symbol.
