Setup.exe - search for package

[Andrew Punch <andrew at magneticbooks dot com dot au>]

Hi,

There is one feature that I have always wanted in cygwin setup - the 
ability to search for packages. This is particularly useful for tracking 
down libraries which are required for compiling some project.

So I have come up with a patch which does that. It needs some tidying up 
but it is already functional.

The functionality I propose is as follows:
* In the "Select Packages" screen I added a new edit box - the search 
edit box. The search edit box is to the left of the Keep/Prev/Curr/Exp 
and View elements
* As soon as the text in the search edit box changes - the list of 
packages is filtered
* If the package name contains the text in the search edit box - the 
package is displayed
* If the View is "Category" when the text in the search edit box changes 
- the View is changed to "Full"
* If the View is NOT "Category" when the text in the search edit box 
changes - the View is NOT changed
* If the View is manually changed to "Category" - the text in the search 
edit box is erased


The patch will need to change the following files:
* choose.cc
* PickView.h
* PickView.cc
* res.rc
* resource.h

Does anyone have any input before I tidy up the code and submit a patch? 
Also I assume the cygwin-patches list is the correct place for the patch?
