windows: restore window position

[redmunds]

Glenn submitted a fix for this on Mac, so now we can take this fix for Windows.

This should use the GROUP_NAME and APP_NAME constants defined in config.h instead of hard-coding "Brackets"

[gruehle]

Oh, and PREF_BRACKETS_BASE should be given a more generic name like PREF_APPSHELL_BASE, too.

[redmunds]

Fixed.

This is for: adobe/brackets#1594

[gruehle]

the GROUP_NAME macro, if defined, already has a backslash at the end of it (see config.h for edge code). In that case, you'll either need to omit the backslash when copying from pGroup, or omit it here before appending pApp.

[redmunds]

Fixed. I made it so any string passed to this function works with or without a trailing backslash.

[gruehle]

Initial review complete.

Looks good. Merging.
