This patch does following things for this purpose:
* Adds intrernal flag to GimpTag api
* Modifies GimpData gimp_data_set_filename to use the last element
  of the path, unless blacklisted, as internal tag for the resource.
* Modify tag cache to not save internal tags
* Removes a check for existing tags when objects are added to tag cache

It was never disconnecting from any of the src_container objects'
signals.

GimpFilteredContainer: unref the src_container in finalize() instead
of dispose() because the parent dispose() impl now needs it via
calling gimp_container_clear().

GimpTaggedContainer: implement GimpContainer::clear() and disconnect
from all the src_container objects' signals.

GIMP now depends on a more recent version of librsvg.

because old versions use deprecated GLib stuff in their headers.
Don't #undef G_DISABLE_DEPRECATED in file-svg.

Don't #undef G_DISABLE_DEPRECATED in help-browser and web-page.

The rgb565 mode of the raw plugin was wrong. Some colors accidentially
got bits from the adjacent colors. Fixed by properly masking the resp.
bits and properly extending them to the 8 bit range.

Use g_format_size() instead of g_format_size_for_display() because
the latter is deprecated.

For the reasons mentioned in the last version bump commit below.

The unsaved "Working Path" was not being loaded from the PSD. Passed
this Working Path resource through the same function call as the
normal path resources, and named it "Working Path"
