When task list is empty, the add new task EditText is hidden by the soft keyborad

[Google Code Exporter]

What steps will reproduce the problem?
1. Open Pomodoro tasks 
1a. Clear Task list if not empty
2. Touch the New Task EditText
3. "New Task" EditText is hidden by the software keyboard

What is the expected output? What do you see instead?
The whole window needs to scroll and the EditText should be positioned on top 
of the soft keyboard

What version of the product are you using? On what operating system?
Latest version on the market 1.4.
I also downloaded the sources from SVN and ran it on my emulator and the bug is 
still present

Please provide any additional information below.
I'm submitting a Patch (attached), let me know if that works or if you want me 
to do it any other way. (direct commit maybe?)
