IIS: Tarball for Windows as well

[zimmerle]

Experienced system administrator may want to use the ModSecurity/dependencies DLLs directly, instead of use our installer. The idea is to provide a Zip file with all ModSecurity dependencies and ModSecurity DLL as long as instructions, so that, those system admin will be able to make their own custom installation/configuration.

Instead of a zip file the msi package now has an option to register or not ModSecurityIIS dll inside the IIS, making possible to install(/uninstall) the files without register the DLL which historically has being shown the problematic part of the installer. Code is under test at branch iis_installer: https://github.com/SpiderLabs/ModSecurity/tree/iis_installer
