More clean-up, portability and another debugger fix (PR #847)
Fixed debugger main "data" window behaviour:
. When activating the main data display ("data" command) the cursor keys wouldn't work until the minidump ("md1") was also enabled. NB. The cursor keys should work in the main data window, independently of whether the minidump is active.
