c4dtools 1.2.0, minor updated

c4dtools library is now in version 1.2.0.
The c4dtools.resource module is now a sub-package.
The c4dtools.resource.menuparser module was added. It implements parsing
MENU resource files, which look like this:

MENU MENU_FILE {
MENU_FILE_OPEN;
MENU_FILE_SAVE;
MENU_FILE_SAVEALL;
-----------------;
# Sub Menu
MENU_FILE_COMMANDS {
COMMAND 5159; # Cube Object ID
}
}

The symbols must be defined in the c4d_symbols.h or better in the
c4dtools.resource.Resource instance passed on evaluation.
