Thanks! - And: mkdir output directory

Hi,

first let me say that this project made my day!
I'm using it in converting the Open Source ERP ADempiere to equinox,
and since that project has quite a complex ant based deployment structure,
a4e is made for me.

One little issue: The Adempiere build scripts remove the output folders
on ant clean.
So in a4e-pde-macros.xml, I added ther following linein line 161, before the javac command:

That's it.

Ah yes, and I reduced the amount of log infos a little bit ;-)
