/**
* Finds all Locale objects representing locales available in the
* FLOW3 installation. This is done by scanning all Private and Public
* resource files of all active packages, in order to find localized files.
*
* Localized files have a locale identifier added before their extension
* (or at the end of filename, if no extension exists). For example, a
* localized file for foobar.png, can be foobar.en.png, fobar.en_GB.png, etc.
*
* Just one localized resource file causes the corresponding locale to be
* regarded as available (installed, supported).
