Ok, I've attached, as a first cut, a diff against SVN HEAD that does (I 
think) what I'm looking for.  It passes all of the old tests and passes 
my own quick test.  A more rigorous test suite will follow, but I want 
this out the door before I need to leave for the day.

What this changeset essentially does is just add support for automatic 
dtypes along with supplying/reading names for flexible dtypes.  It 
leverages StringConverter heavily, using a few tweaks so that old 
behavior is kept.  This is by no means a final version.

Probably the biggest change from what I mentioned earlier is that 
instead of dtype='auto', I've used dtype=None to signal the detection 
code, since dtype=='auto' causes problems.

I welcome any and all suggestions here, both on the code and on the 
original idea of adding these capabilities to loadtxt().
