Reverted the change to ARM.py from dc68b76

Fixes one of Emilio's problems :D
Removed extra core_* files that are no longer needed. Makes Emilio more happy.
Removed unnecessary LPC1114-specific test.
Reverted unnecessary change to settings.py

Also keeps the GCC_ARM_PATH in keeping with the rest of the code, rather than looking out of place.
Tidied up one line of targets.py

Removed an extra indent.
Addition of a newline to the end of gitignore

To stop github pointing it out to me that I've missed a new line :O the horror!
Removed non-functional LPC1347 uVision export support, and added LPC1114 support, which does work.
Merge branch 'forpullrequest' of https://github.com/matthewelse/mbed into forpullrequest
Added alternative DIP package names for pins in the LPC1114

Added this so it is consistent with the notebook page.
Merge pull request #17 from matthewelse/forpullrequest
