Edging closer to a working rewrite

This alpha release continues to (re)add more of the features of v1.0 but with changes for consistency and internal flexibililty.

A variety of positonal arguments have become explicit flags for each command, for example to remove an instance config item you may have used:

geneos set gateway test -key

Now, there is an expicit unset command and a -k flag, e.g.

geneos unset gateway test -k key

Other positional parameters have moved too and you should check the help output for commands if something doesn't work as expected.
