Stop compilation on the first error, and highlight it first

Highlighting the latest code syntax error makes it more difficult to find the line of code causing problems...

Example:

Class classname();
classname.doThis(); <--- # 1
classname.doThat();
classname.doThatAgain(); <--- this line is highlighted in case of error, instead of # 1

I don't know if I'm clear... Thanks

Reproduce the example in the Arduino IDE 1.x and inspect how compilation errors are reported and highlighted. Done means compilation stops at the first syntax error and highlights that line rather than a later error.
