command UI only has one command

[jmesserly]

The new modular compile uses the commands package in arg:

dartdevc compile -o module.js foo.dart bar.dart

the idea was if we add build or watch or serve, it makes sense to have a different set of options for those commands (e.g. a compiler should't take a server URI/port as an option :) ). But in recent discussions, we've started to think if maybe those are different entry points, in which case we only have compile and link. Not sure if it's worth a full command split for just those two.

Anyway, wanted to file an issue to track this. No action needed but we wouldn't want to ship 1.0 in this state, IMO. :)

CC @vsmenon for thoughts. This is not an urgent one though, just something to think about.

Part of my thought here, I can't think of a lot of other modular compilers that have a full command split (unlike, say, package managers or version control systems where it is very popular). Probably best to stick with existing conventions.

Also, the commands broke the script in the Dart SDK.

Fixed, we still support "compile" for backwards compat
