Run your unit tests individually using Flute

[Robert Fraser]

Okay, it's not actually done, but since I'm changing the interface to a 
network-based/socket one that will be less viable for command-line 
usage, I thought I'd announce the command-line version now.

Flute is a natural extension of UnittestWalker which allows you to run 
unit tests one at a time, run only specific tests, track failures, 
errors, and passes, etc., etc. It integrates directly with D's unittest 
construct, so no additional coding on your part is necessary, just link 
in the Flute module and enjoy! If you want to name your tests, you will 
have to introduce a dependency on the naming module, however.

If all you want to do is run all your unit tests & track whether they 
pass or fail, use UnittestWalker, which can already do that. Flute is 
better if you plan to run your unit tests one by one.

Flute will hopefully soon be integrated with Descent which will give a 
UI for you to track & run specific unit tests, change the source and 
instantly re-run a particular test (hopefully with all the compilation, 
etc. being transparent), etc.

However, since there's _not_ a UI right now, I'd suggest (once you get a 
feel for it), piping input to stdin so you can create your own test 
suites that run only particular tests, etc., since re-typing all those 
test names won't be fun.

In its current form (which will likely be the final command-line form 
unless someone wants to fork it), it doesn't support D2. I've actually 
only tested it with DMD 1.020 on Windows. It should work on both Tango 
and Phobos, but again I've only tested it on Phobos 1.020 and Tango 
0.99.2, so I'm not 100% on that.
