Single Session GDB

I have upgraded GNU ARM Eclipse plugin (1.8.1.20140218) and the new version comes with an OpenOCD Debugging Support (1.1.1) - a Debugging Configuration tailored for OpenOCD.

This Plug-In provides a "Restart Button" which makes whole build process even simpler and more seamless.

Instead of current "GDB Hardware Debugging" style:

1. Launch GDB
2. Program uC
3. debug
4. stop GDB
5. edit source
6. build
7. goto 1

with new plug-in it is enough to run only single GDB session and rebuild without terminating GDB!

1. Launch GDB
2. Program uC
3. debug
4. edit source
5. build
6. press "Restart" button (also programs ram)
7. goto 3

Isn't that great?
It cannot be simpler than that, can it?
With next commit I am going to switch from legacy "GDB Hardware Debugging" to "GDB OpenOCD Debugging".
