Commit the original Caesium 1.7.0 codebase with some adjustment.
You can also get the original source at:
https://sourceforge.net/projects/caesium/files/1.7.0/
Since the file names listed in the Qt resource file have encoding
issue which can cause compile failure, these files get removed.
Adjustments:
+ .gitignore
M icons.qrc
- *.pro.user(.*)
- icons/language/*.png
