kll compiler doesn't warn when missing a semicolon

last commit when getting this issue: 6ea6b7e (kll), e94a6562 (controller)

When using the default kira keymaps (release.1.kll), replacing the 2 layer combinations at the top by:

### Custom key mappings
 
U"ESC" : U"CAPSLOCK"
U"CAPSLOCK" : U"ESC"
 
 
### Layer Combinations ###
 
U"RCtrl" + U"F1" : Layer[1];
U"RCtrl" + U"F2" : Layer[2];
U"RCtrl" + U"F3" : Layer[3];
U"RCtrl" + U"F4" : Layer[4];

(note the missing semicolons before the layer combinations comment)

The above kll will compile file, the compiler will not output any warning, but ESC and CAPSLOCK will not be interchanged, and layer switching (RCTRL+F1) will not work.
