Support Java alias for jshell

The `jshell` alias currently imports libs like guava and jOOL into the `jshell`,
which is nice for experimenting.

Experimenting with keeping some helpful `.jars` in `~/programming/jars`. This
may be a bad idea, and there may exist a more idiomatic way to do this instead
of wrapping `jshell` in an alias, but for now, I need to move on.

Also documents some abbreviations for applications. `jv` will be necessary so
that I don't conflict with `j` or `js` for javascript. Eventually I'll need to
be more organized to avoid naming collisions, but this is okay for now.
