[Translation] example code did not work.

The example code for Translation did not compile. And the trans() result was void.

[Console] Exception rendering fixes

This fixes two things:

- `\r`'s in exception messages were output (in case of `\r\n` newlines), creating really weird results on windows.
- long exception messages were wrapping and then the "red" block was completely messed up, with half black/half red lines, now it's wrapped before output if the terminal width can be detected.

If you don't care about merging this for 2.0, you can also merge the `console_ex` branch which applies on master. Due to moving tests and renaming of some normalize stuff in the tests, the two test patches are kind of different.

RFC: I am really not sure where to put those getTerminalWidth/Height methods. I guess this is not the best place.

[Console] Fixes terminal width in tests

This fixes the [tests that broke on travis-ci](http://travis-ci.org/#!/symfony/symfony/jobs/1031109) (which seems to advertise a terminal width of ~34, not sure why).
