v0.4.4 !

- Projects can now use either loadresources.xml or
loadresources_debug.xml, or none (as before). This must be selected at
project creation and cannot be changed.
- NPC and Items comparators now include both the source and altered
version of elements present in both.
- Spritesheets view should now be better laid out, as insets were not
taken into account, thus cropping a few pixels right and down.
