hgk issues on win32

[Bela Babik]

I was able to get hgk working on windows.

I had 2 problems:

- The default selection color for me is a kind of dark blue on the
canvas which makes the selection unreadable. I have added "
-selectbackground grey" to each one.

- The hgk.tcl assumes "\n" line endings so it is unable to parse the
output of hg on windows. I created a batchfile, and it is working now:
@C:\Python24\python.exe C:\Python24\Scripts\hg %* | tr -d "\r"
