1.5.2a1 First alpha release for testing

[Rob Braun]

A 1.5.2 bug fix release is planned, and the first alpha has been
made available at:
http://xar.googlecode.com/files/xar-1.5.2a1.xar

This release includes some build system changes to allow
static and dynamic libxar, use of finer grained makefile
variables to allow build systems to more easily control
where things are installed, 2 bug fixes from the rpm5
project, and a bugfix for when xar is processing a malformed
table of contents.

Please give it a try and as always, report any issues through
the xar issue tracker at:
http://code.google.com/p/xar/issues/list

Thanks,
Rob
