postgis-gui lacks transformation support

[robe]

We've got transformation support in shp2pgsql with the srid_from:srid_to syntax, but we lack the same feature in the shp2pgsql-gui. To implement a number of options come to mind -- I'm leaning toward 3. Any thoughts on the matter before I attempt to implement?

1) We add a TO srid column in grid and if blank we assume same as SRID and if filled in we transform. I don't like this cause it takes up more space and may confuse some people as to what field they need to fill in.

2) so we don't make gui change -- we could change the allowable input in SRID to allow the : syntax, though that has the annoyance of not being obvious to the user that its a new feature unless they expect it. Some users may just try it though and hey it works (as opposed to being frustrated now when the thing just replaces what they typed with one of the srids)

3) Have the To SRID show in the Options dialog with the mind set that when you are loading a bunch of tables, you generally want the results spatial ref sys to be the same though the input one may be different for each table. It also minimizes on confusing newbie users who will then be confused which field they should fill in SRID or SRID_TO or both.
