This commit updates the gradle files to be cleaner. It also builds for the

current platform by default, and only builds tests when building for the
current platform. Mac builds and VS2015 builds are fixed.

The other big change in this update is the introduction of Debug and
Release builds. Debug builds are built with -O0 and -g. Release builds are
built with -O2 and -g. For GCC-based builds, the resulting shared object
is copied, stripped of debug information, and a debug link is set up to
the copied shared object. This allows the release build to clock in at
around 600 KB. On Windows, the debug info is already stored in a separate
PDB file, so this copy and strip is not necessary.

ntcore is being separated out from the rest of allwpilib. All other
builds will consume a published maven dependency from this project.
There are 4 possible publishing targets now: release, stable, beta, and
development. These are specified on the command line via -Prepo=<repo
name>.
