Add support for Live Soft Action installers (LopeSoft)

I came across an installer that has a cluster of offers Unchecky misses before actually downloading and executing an msi for the product in question. The downloader is available here. (LopeSoft FileMenu Tools)

I had some trouble identifying the company behind the actual installer. It doesn't look like something LopeSoft themselves designed.

I noticed that it downloads the msi to a temporary folder. A more efficientway of bypassing the downloader/installer could be something like the following:

1. Detect a downloader / installer of this type.
2. Determine the URL the downloader intends on using by examining the EXE. (hopefully this is possible)
3. Terminate the installer / downloader (possibly notifying the user.)
4. Download the MSI / installer directly.
5. Execute the downloaded file under the same user account the downloader was initially executed as.

This process may also work for downloaders like the CNET downloader.

Alternatively, a browser extension may be able to redirect the download to the actual installer instead of the downloader. I'm not sure how possible this is.
