Tweaks: SQL Query Tool

Hi guys.

Herewith submission for tweaks to the Code completion / prompt feature :-

Minor tweak 1: Remove additional space inserted
After the Ctrl-Space selection, two spaces are inserted.
This is unnecessary unless it was to cater for key sequences other than
Ctrl-Space.
(I am not aware of how to change the initiation sequence from Ctrl-Space)

Minor tweak 2: Selection list scrolling
Allow jump-to scrolling of the selection list using key-strokes.
Currently only the arrow keys are of any use.
(First letter typing escapes the dialog and inserts that letter)

Enhancement Request: Additional invocation points
Currently Ctrl-Space only seems to work for the first field selection
after a WHERE clause
If possible, allow invocation after AND, OR, JOIN, JOIN xxxx ON etc.
Also allow it after the period with TableName-dot-Fieldname syntax.
