file path for nxt cross compiler resources does not work + cross compilation errors on windows

[Ch40sl0rd]

When using the Open Roberta Lab on a Windows machine, the path for the nxt cross compilers is given es e.g.: "C:\Users\Lars\Documents\ORB_dev\crosscompiler/RobotNXT//windows/nbc.exe" which mixes forward and backward slashes and thus is not a valid path on a Windows machine.

Because of this the cross compiler resources for NXT can't be found on a Windows machine.

In addition to the above, there are cross compilation errors encountered on Windows machines for multiple robots:

• Robots under RobotArdu project:

Add more installation steps for relevant robots in the README file.

I wasn't able to reproduce the error for NXT, but found errors for other robots instead! @Ch40sl0rd, could you please confirm if you still get any errors for NXT?
