Bug 990481 - [ZTE][OPENC]MMS app allows to attach more contents even whe...

...n the max MMS size is reached
nit: space between ```//``` and ```enable```. I think it would be better to have smth like
```// Lock composer when size limit is reached```. Also please use the following comment notation for the methods/functions [1]:
```
/*
 * Description......
 */
methodName: .....
```

I know we don't have consistency everywhere in the code, but now we're trying hard :)
