Changed the naming scheme used in Konsole.  Several survey respondants said that they didn't understand what a 'Session' was or how it was different from a 'Profile'.  Under the new scheme, a 'Profile' is a saved set of terminal options which can be used to create a new tab, or which can be applied to an existing tab.  Internally, a 'Session' is a running terminal process and emulation created from a particular profile.
