WinGui:

WinGui:
- User presets and built in presets are now show in seperate colours. User preset's are shown in black and built in are blue.
- Added cancel button to add preset.
- Removed File Menu > Import. This is not required. Users can import old .hb files as text into the query editor if need be.
- Adding a new user preset no longer stores Title and file input/output information. While these were never used, it's a waste of space storing them in the user presets file.
- Added a comfirm dialog for removing presets.
