[PATCH] Change timeout to runtime and rearrange option entries

Runtime is a more descriptive name - the documentation is updated
as well, however the parsing has added an alias functionality to
support older names as well. So 'timeout' still works.

Also rearrange option entries, now they matter because the --cmdhelp
option will print them in order.
