Preferences: remove tweak/drag threshold distinction

Browse Source 
Currently the preferences have both tweak and drag threshold,
this is confusing because most actions users would consider
dragging use the 'tweak' setting.

Now one drag threshold is used for both, with a maximum limit of half
the button unit-size in case of dragging UI elements.
