Shorten LocalPeer socket names

Browse Source 
On most systems supporting Unix sockets, the maximum length of a socket name is quite low (e.g. on macOS 104 characters and on Linux 108). If the name is too long, the sockets will not work and thus sending messages to a running instance of the launcher will not work.
