Added feature that set text by intent.

I added a feature that allows you to enter the code with the intent.
In addition, I have also added the ability to easily enter the code in via adb.
Example:
```
% ./ajsha.sh
Please input your java code.(Press Ctrl+D to exit)
Toast.makeText(ctx,"test",Toast.LENGTH_LONG).show();
exit
Starting: Intent { flg=0x4000000 cmp=org.ligi.ajsha/.EditActivity (has extras) }
```
