Ant 1.7.1_beta2 hits java-experimental overlay

Hi,

looks like after about year and half after 1.7.0 we will see a 1.7.1 
release of Ant :) Beta2 was released recently, check out release notes:
http://people.apache.org/dist/ant/v1.7.1beta2/

I'm gonna commit it now to java-experimental overlay, and took this 
version bump as a chance to implement some changes:
- completely phasing out ant-tasks package which is now possible because 
nothing depends on it anymore. The USE flags that trigger the deps on 
individual tasks will move to dev-java/ant package
- the compatibility symlinks to /usr/share/ant/lib/ that were created 
for all tasks in ant-tasks are split will move to the individual tasks 
instead of dev-java/ant, so they will be created immediately when the 
tasks get installed and not on depend on the USE flags in dev-java/ant
- this means there will be a blocker to ant-tasks (unversioned), 
hopefully this time it's really the last blocker during the upgrade :)
- ant-core installs the style sheets in etc/ as the binary upstream 
distribution does (Betelgeuse once said something expected them but 
probably never filled a bug)
- EAPI=1 slot deps are used for external package dependencies. Some deps 
were converted to RDEPEND only to be more accurate.
- ant-trax no longer depends on ant-junit because upstream moved some 
classes around. This could probably break some packages if they depended 
and used in ANT_TASKS only ant-trax but need also junit.

Did some basic testing using remerge-everything-java script from the 
overlays svn, catched some errors of mine, no upstream breakages yet. 
Testing and bug reports of course welcome.
