Use a dict with update() to manage default configurable values in pythontest

gcompris_change_locale and gcompris_reset_locale are usefull fonction to change locale easily in boards. colors uses it, and pythontest.
Fix configuration window behaviour: now the window closes when "Apply" button is clicked.
add a asset_get based gcompris_get_locales_asset_list: really to long, needs to be rewritten. unusable.

add gcompris.gcompris_gettext method to call C gettext from python. python gettext does not accept reread it's translation file if environnemnt's LC_MESSAGE is set to a not registered locale. Seems works, but needs more check.

add gcompris_combo_locale to add easily a locale choice for board.

Patch to fix compilation (libdir and X path) in x86_64, by Göran Uddeborg, thanks. Python need another check.

add gcompris_locales_list.

make <span size='large'> the label title in the conf.
use a list and not dict to control combo in pythontest.
add a label in filter boards tool.

gcompris_spin_int configuration utility function, for integer valued spin buttons. Binded in python (gcompris.spin_int). Sample in colors.c and tuxpaint.py.

 GHashTable with (key, label) pair, return the key of the value selected.
python binding is missing.

	Very impressive how he made this user friendly. Much
	better than what I did in the configuration panel.

	- Prepared the login screen but empty for now
	- Renamed reread_xml by reread_menu
	- Now the noxrandr param is 'almost' persistant in the config file
	  'almost' because until you enter and quit the gcompris config
	  panel, it is not saved. This is very dangerous becaus after that
	  there is no way to put back xrander in since there is no --withxrandr
	  switch.
	  WARNING: This need more works !!

	Completed the code, added some checkings.
	Still need some testing.
	Made the icons.

	the wholegroup is updated automatically

	Added contextuality to buttons in class and profile list.

	edit the class name and teacher.
	The whole group is now created but not populated.

	  It is now started with gcompris -a
	- Reworked modules statup to work like Yves did
	- Reworked class edit to also edit the class name and teacher.
	  In the end it will not be possible to edit in the tables anymore.
	  This still does not update the parent list.

add label option in gcompris_configuration_window fix tuxpaint.py and colors.c for use it.

	gcompris -p or --profile name => run gcompris under the profile 'name'
	gcompris --profile-list => display on stdout the available profiles

fix segfault.
fix tuxpaint to work effectively with new configuration funtions

gcompris_configuration_window and gcompris_boolean_box: two usefull functions for boards configuration, with python bindings
samples in tuxpaint.py and colors.c

	Completed support for Nepal

	Added a default class and it's all group for Unassigned users
	When user are removed from a class, there are moved there automatically.

tuxpaint launcher configuration is now working ! Yeah!

Add pref icon in treeview if board is configurable
gcompris_load_menus_* skip boards listed in profile unactivated activities. (Works !)

	Implemented the management of the default profile.
