rc2.2.5 (install.sh) relative path fixes (#2155)

* (installer) fix bug in resolution of relative paths in linux install script

point installer at 2.2.5-rc1

selecting ~/Data/myapps/ as location  would create a ./~/Data/myapps
instead of expanding the ~/ to the value of ${HOME}

also, squash the trailing slash in path, if it was entered by the user

* (installer) add option to automatically start the app after install

also: when exiting, print the command to get back into the app
