Preferences should be reviewed and defaults fixed

[Keith Brown]

Some of the preferences may not actually be used, and if they are still used they should have their default set appropriately for the system it's installed on.

Example: Preferences -> General -> Endline character
This option defaults to "LF (Unix)" even on a windows system. Martyn Giggs mentioned that this property might not even be used. If that property is used it should default to the appropriate system Mantid is installed on and if it's not used it should be removed.

All the properties should have this done for them in order to remove redundant options.

Cleaned up default separator and newline preferences

Both import and export ASCII use same newline and column separator values from preference window

Windows newline should default to CRLF

So far have tested everything under General, Tables, 2D Plots and 3D Plots.

Almost all settings under there seem to be working (at the very least they update the settings of another system (e.g. antialiasing seems to do very little but is being enabled/disabled)).

Still to test:

• Mantid/Curve Fitting

Import and Export ASCII now get their EOL value from that defined in preferences.

All other preferences are at least used to set a value in a different system.
