setting alarm limit - cursor position about boilr

[dllud]

When we coded that part I spent some time trying to implent that but could never achieve it.

Moving the cursor of the EditText which is inside the EditTextPreference does not work from the PreferenceFragment. That is, one cannot move the cursor before the EditText is visible. In order to solve this we would have to implement a custom EditTextPreference.

Therefore, I prefer to postpone this to when we tackle #48. Then we will have to create a custom Fragment using EditText boxes whose cursor is fully controllable.
