created Partdesign_Hole, Tree_PartDesign_Pad, and
Tree_PartDesign_Revolution SVG icons
Referenced the above in the PartDesign.qrc file
Modified the ViewProviders to display the Tree_icons
for Chamfer, Fillet, Draft, Groove, Hole, LinearPattern,
Mirrored, MultiTransform, PolarTransform, Revolution,
Scaled, Pad and Pocket.
PartDesign_Hole has not been implemented yet however
the ViewProvider has been, so I added the icon
* Updated the updateTranslations.py tool so it can now work with
unzipped folders, and it updates qt resource files when necessary.
* Updated existing translations, changed a couple of language codes:
es -> es-ES, pt -> pt-BR, zh -> zh-CN, se -> sv-SE
* Added new translations that have more than 50% translated:
cs, hu, ro, sk, zh-TW, tr
