allow numerical start and allow dots in ssh alias

Browse Source 
We previously restricted the ssh alias to start with an
alphabetic character and did not allow dots within it. This caused
problems with users wanting to use an ip address as an alias. This lifts
that restriction so both can freely be used.

Note that while it is common to use the hostname as the alias, hostnames
are not allowed to use the underscore character. However, we do allow
the alias to contain an underscore. I do not think we can remove this
from aliases now but it is something to watch out for in the future.
