Patch by "jwlh172": Added a text control to the partition

creation panel of DriveSetup, to enter the partition size
manually. Closes ticket #7991. Changes by myself: I've
refactored updating the text control from the size slider
and used that method also when the user somehow entered
invalid input into the text control (untested).
