Provide shortcuts navigation plugins for bookmarking resources / returning to bookmarks

the "mark" and "go" commands would be useful

$ go home
$ go project
$ mark javasrc
$ cd ~/
$ go javasrc
takes you back to that dir
with tab-completion of course
$ go java<TAB>
$ go javasrc

// go without an argument lists the available targets
$ go
home (global)
project
javasrc

By default, "mark" adds the bookmark to the current project's /META-INF/forge.xml
the --global command would redirect these settings to the ~/.forge/forge.xml or ~/.forge/config file

$ mark

{name} --global (default command?)
$ mark add {name}

--global
$ mark del

{name}

--global
$ mark list --global
