Cleanup: remove and/or fix some confusing comments

The comments for SettingDescType; it is a byte, so not 4 bytes and since it is not a flag there are about 250 other possibilities left instead of 9.
SettingGuiFlag is uint16 so has 2 bytes allocated.
SettingDescGlobVarList and related comments imply that global vars cannot be used elsewhere, but they are used for settings just fine. Even then the type is not used anywhere else but the definition of the table.
