Profile-bound custom commands now execute

Rather than starting ksession right away, PreprocessedTerminal now waits
for ApplicationSettings to finish loading custom command settings from
storage. If a custom command is specified, PreprocessedTerminal will
tokenize it and pass it onto ksession as a shell program similar to the
-e option. If both a -e command and a custom command is specified, the
-e version overrides the custom command.
