Add an editable version of the string picker, which allows you to edit each of the strings inline and even add new ones.
This just implements the guts of the dialog, without using it for anything yet. It also fixes a bug that caused a blank page to appear in the string picker if the total number of strings was an exact multiple of 40. Closes #563
