Replace \x1b with \e

Do not merge yet

My IDE suggest me to replace \x1b characters with \e.
I've done the replace only in tests to check if some thing breaks.
Is this a more optimized way to write the same character?

Reading the web I see that \x1b is equal to \e and to \0x1B and \033.
That's ever the same character.

I prefer \e because it's more readable.

But what about these lines https://github.com/phpmyadmin/sql-parser/pull/130/files#diff-5897b34c7e97d0c27240a808838bc33eR371?
Where text\e[33m will become text\\x1B[33m

If it's ok for you I can continue with this PR.

:-( I see now the results from travis, it seems that php5.3 does not support parsing of \e characters.
Closing.

That's exactly reason why we don't use it, see 3ece9ee.

OK, good to known.
