Update README.md

Since our gdb support got much more user-friendly, all the quirkiness of getting debugging to run no longer apply.

-### Debugging
-Starting with Visual Studio 2015, the IDE is capable of using GDB as a debugging backend.  
-Visual Rust now supports this feature!
-
-#### Pre-requisites
-- You will need to install GDB for Windows from one of the [MinGW-w64](http://mingw-w64.org) distributions **(original [MinGW](http://www.mingw.org/) won't work)**.
-- When installing Visual Studio 2015, be sure to put check mark next to 
-'Tools for Visual C++ Mobile Development' component.  This will install the GDB front-end package.
-
-#### Configuration
-If GDB installation directory is on your PATH, no further configuration should be required. 
-Otherwise, open `Tools/Options...` dialog in the IDE, navigate to `Visual Rust/Debugging` and 
-enter the full path to gdb.exe there.
-
-#### Usage
-Most of the usual VS debugger features are supported.  
-You can also issue GDB-specific commands in the VS Command Window: `Debug.GDBExec <command>`. 
-For convenience, `Debug.GDBExec` has been aliased to `gdb`.
-
-#### Known issues
-- The 64-bit GDB fails to start 32-bit executables. This appears to be a GDB problem. 
-Meanwhile, you can use the 32-bt version of GDB for 32-bit debugging.
