Title: Windows installer: do not write to Software\Microsoft\MediaPlayer\ShimInclusionList registry key

The Windows Media Player application has a list of processes executable files which are allowed to launch it. Zotero's installer was attempting to add itself to this list, but was not doing so correctly. The installer was not initializing a variable to the correct value before writing to the registry. Instead of Zotero's process name, the strings "true" and "false" were being added to ShimInclusionList. The uninstaller was then failing to clean up the registry.
