WinHugs, new installer

[Neil Mitchell]

Hi,

Attached is a new installer for WinHugs. Its custom written, and has
been used successfully on Pingus for years [http://pingus.seul.org/].
This version has some modifications.

I have placed 2 screenshots at the bottom of
http://www-users.cs.york.ac.uk/~ndm/projects/winhugs.php

The code is at http://www-users.cs.york.ac.uk/~ndm/temp/installer.zip

Advantages:
100% open source
100% customisable
Registers Open and Edit via winhugs, along with a new document handler
for windows. This removes the need for WinHugs/register
Cat'able package creation (see how to create)
29Kb overhead vs just distributing a zip
Can be opened by winzip, if people want
Looks pretty

Disadvantages:
No cancel once you start installing, I don't think this is such a big
deal, but it can be remedied with effort
No uninstall, I will fix this before release, but again its not a
massive problem since a winhugs install is pretty non-invasive

Creating a package:
Get a directory, as you want it installing
Zip it up
copy /b installer.exe + installer.zip winhugs.exe
distribute winhugs.exe

If you just unzip the linked file into /src/winhugs/installer it will
all work perfectly.

Once this is in, I'll put together a winhugs snapshot for people to
beta test. I am now using WinHugs as my primary haskell development
environment, and so are at least 3 others. Its solid and very useable.

The code is C++. I would appreciate it if the formatting was not
changed (i.e. tabs and spaces, bracketing placement) as then it will
be easier to sync it with Pingus, since the code is already in their
.svn.

Thanks

Neil
