Improve detection of Visual C++ 2008 Redistributable

[lunch]

Currently the installer doesn't check for the latest versions of Visual C++ 2008 Redistributable.
As a result, if the user has the latest version of these runtimes installed, it isn't recognized and he is prompted to install these. As more, an older version.

Relevant file: deluge-win32-installer.nsi

CLSID currently checked:

• FF66E9F6-83E7-3A3E-AF14-8DE9A809A6A4
• 9A25302D-30C0-39D9-BD6F-21E6EC160475

You should add these two entries:

• 1F1C2DFC-2D24-3E06-BCB8-725134ADF989
• 9BE518E6-ECC6-35A9-88E4-87755C07200F

I think you should also remove FF66E9F6-83E7-3A3E-AF14-8DE9A809A6A4, so the user would be prompted to update its antiquated VC++ 2008 redistributable to at least SP1.

Lastly, I would update the download link to https://www.microsoft.com/en-us/downloa ... x?id=26368 in order to direct to the latest version.

Thanks didn't know about that security update, I'll just update the SP1 CLSID for latest security update. I know there is mention that the SP1 redist version can have problems with python, Deluge looks to be fine but rather err on side of caution and leave non-SP1 check in there.

Ouch, I wasn't aware of this version issue...

Some links:

• http://www.py2exe.org/index.cgi/Tutorial#Step5
• https://sourceforge.net/p/py2exe/mailma ... /27220164/
• http://stackoverflow.com/questions/2017 ... l#20306053

I had a quick look at deluge.exe and python27.dll's manifests, it's 9.0.21022.8.

So to be on the safe side, maybe we should check only for non-SP1 runtime and install this version if absent?
