verified to work on real robots
adds sim eclipse plugins, fixed JavaGazebo, made wpilibC++Sim build on windows
 - Java and C++ simulation robot programs run on windows
 - simulation eclipse plugin delivers models and gazebo plugins
 - Java Gazebo now respects GAZEBO_IP variables and can work across networks
 - hal and network tables win32 hacked to work on windows
 - smart dashboard broken on windows due to network tables hacks
 - wpilibC++Sim, gz_msgs, and frcsim_gazebo_plugins build with CMake
 - removed constexpr for cross platform compatibility
 - msgs generated using .protos as a part of build process
 - some spare and unused cmake/pom files deleted
 - simulation ubuntu debians removed entirely
 - refactored CMake project flags and macros

Building everything requires Maven, and the arm jdk
To build eclipse plugins (also build wpilibc/j)
========================
./gradlew eclipsePlugins //this is what is most often used
other possible targets are "build" or "frcuserprogram"
To build on CMake Projects (gz_msgs, frc_gazebo_plugins, WPILIbC++Sim
=========================
//STARTING FROM ALLWPILIB DIRECTORY
$> mkdir build
$> cd build
// on linux
$> cmake .. && make -j4
// on windows
$> ..\configure.bat
$> jom
## You can build subprojects of CMake stuff
To find all of them, you can navigate to "build" and type "make <tab> <tab>"
Examples:
make WPILibC++Sim
make dc_motor
make gz_msgs
make clean
## Note: For the latest version of FRCSim that uses the NI Driverstation, there is a circular dependency between CMake and Gradle projects.
wpilibc++sim depends on hal which is gradle, but eclipse plugins depends on wpilibc++sim which is cmake
so if you want everything to work nicely, run:
./gradlew :hal:build
mkdir build; cd build //if you haven't already done so
cmake .. && make -j4
./gradlew eclipsePlugins //or whatever else
Other gradle options
========================
./gradlew tasks //list some available tasks

GCC versions
------------
Update arm-toolchain.cmake if the triplet changes (eg using Ubuntu repo arm compiler is arm-linux-gnueabi) or in a non-standard location. Currently it assumes that the compiler is on the path.
