Window Installer:
A couple of fixes:
- uninstaller now deletes itself (oops! :)
- uninstaller now correctly locates .blender for removal.

Reverted win installer to give 'current user' option only for Application Data.
Added shfolder.lib linking for win9x SHGetFolderPath() support.

Bug fix for 8634, 6708, and 5989

This replaces the hard-coded '%PROFILE%Application Data..." path
with the correct language-dependant CSIDL_APPDATA.

PLEASE NOTE!

Checks for the previous location have now been REMOVED. Any data
saved in the old hard-coded location will no longer be found by
Blender (this will only affect users of non-english windows.)

The installer has been updated to help the user to migrate their data
to the new location of their choice, if necessary.

Order of preference for .blender on windows is now the following:

1) %HOME% environment var
2) Installation Directory (location of blender.exe)
3) "Current User" (CSIDL_APPDATA)
4) "All Users" (CSIDL_COMMON_APPDATA)

NSIS Installer:

Committing the changes used for 2.45 and the upcoming 2.46 release :)

(Better late than never!)

Copying python25.zip to install folders for win32.
Also, nsis installer now copies plugin include headers.

Added a check to installer for runtime dlls required to run blender. If
not found on their system, it will open a browser window to point them
at the download site.

DEV NOTES: Anyone building the NSIS installer will need the Moreinfo
plugin - http://nsis.sourceforge.net/MoreInfo_plug-in

Added windows NSIS installer script to scons. Not pretty, but it works :)

To use:

Make sure NSIS is in your %PATH% and type 'scons nsis'

It doesn't currently compile blender first, so make sure you do a
normal 'scons' before this.

Corrected IThread.lib to IlmThread.lib.. thanks Stephane :)

Updating scons VC config to OpenEXR 1.4.0

Small change to keep MSVC happy -- defined variable at the start of a conditional block.
