Added persistent storage of text layers in XCF files. We use a
parasite in order to keep the file format backwards compatible.
Fixes bug #111781.
* app/text/Makefile.am
* app/text/gimptext-parasite.[ch]: new files that hold functions
to convert a GimpText object to a GimpParasite and back.
* app/text/gimptextlayer.[ch]: added an ugly hack that allows to
convert a normal layer to a text layer.
* app/xcf/xcf-save.c: when saving a text layer, store an extra
parasite that holds all information about the text.
* app/xcf/xcf-load.c: if a "gimp-text-layer" parasite is found and
it can be successfully deserialized to a GimpText object, convert
the layer to a text layer and remove the parasite.
* app/Makefile.am: had to change linkage order.
* devel-docs/parasites.txt: documented the new "gimp-text-layer"
parasite.
* app/text/gimptext-parasite.[ch]
* app/gui/session.c (session_save): plugged minor memory leaks.
