This provides additional improvements and updates for building
Audacity using Xcode 5.1 or above.
The whole configure/makefile system is no longer used during
normal builds. During library additions/updates it used to
regenerated the headers in mac/config.
which was caused by the fix for Lame and FFmpeg detection. Now,
the Audacity.sh script will only be used for "release" versions.
2) Provides a new "Manual" target that the developer can use to
retrieve the Audacity manual and put it in the "help" directory
to facilitate testing.
3) Provides a new "Plugins" target that the developer can use to
build the 3 Ladspa plugins that are distributed with Audacity.
They will be built into the "plug-in" directory. The main
reason for this one was because no one could remember how to
build them, so now it will be available to everyone.
4) Supports the "install" build action for creating an output
direcotry that is fully distributable. (DMG and ZIP creation
will be added soon.) This provides the ability for anyone
to create Mac releases.
