[josm-dev] jar compression level; JOSM takes too long to compile

[Sebastian Klein]

Hi,

Frederik Ramm changed the jar compression level to maximum (9) in r2368. 
While I thank him for bringing this up, I would rather set it to 0 
(uncompressed).

This is because I spend quite some time waiting for JOSM to compile and 
compress.
This is what I get:

comress level         time for dist task
---------------------------------------------
9                               6-7 s
default                     4 s
0                               2 s


For the releases we need of course level 9. So the scripts for the 
nightly builds would run

 > ant -Dclevel=9 dist

And use this parameter in the ant file:
