Add harbor server command

[sam]

Add harbor server command. For now just default to mizuno for JRuby and rackup for MRI.

Added for MRI in 9c9e57c.

Having trouble with rackup under JRuby. Getting a vague ERROR -1 message on request and no response. Actual web-servers work fine so I'm guessing it's something in jruby-rack. I'll call this one done and the step beyond will be in the 1.1 milestone with Jetty integration.

I tried running the command under JRuby but it didn't work out:

LoadError: no such file to load -- /home/fabio/projetos/oss/harbor/lib/harbor/commands/../jetty
           require at org/jruby/RubyKernel.java:1042

            (root) at /home/fabio/.rvm/gems/jruby-1.6.7/bin/harbor:19

Are we missing Jetty jar or something like that?

I'm running jruby 1.6.7 (ruby-1.9.2-p312) (2012-02-22 3e82bc8) (OpenJDK 64-Bit Server VM 1.6.0_22) [linux-amd64-java] down here

BTW, rackup seems to be working fine down here with that JRuby version + rack 1.4.1 and jruby-rack 1.1.4

@fgrehm The Jetty stuff isn't done yet. So that's why it doesn't work under JRuby.

Maybe it's just my version of jruby-rack that was having issues with Rackup then.
