This update is a major refactor of how LinuxGSM updates itself.
* will now use a version tag if downloading module for the first time.
* added backup repo (Bitbucket) that will be used if Github is unavailable.
* added ./gameserver and module version comparison this will allow instances to be correctly updated if there is a version mismatch.
* UI changes when modules are fetched for the first time
* added sessionname to fix broken tmux session is ./gameserver is called ./gameserver.sh
* change apt to apt-get as recommended by the apt packages when dealing with scripts.
