IsMemberOf is called for every file (in the ownCloud directory or not) and with every instance of OCOverlay (we have 5) when displaying a list of files in Explorer. Refactor the code to avoid copying the list of watched directories, as well as creating a wstring from a PWWSTR for files outside watched directories. Also change some calls of begin_with to use isDescendantOf since it properly handles parent paths not ending with a backslash, which could lead to SocketAPI queries for sibling folders with a name that starts with a watched folder name.
