Bug: adding colors to cells breaks cell width sync between header & body

[webketje]

I wanted to have colored text in cells using chalk, which adds this type of unicode chars: \x1B[32m<text>\x1B[39m. The coloring works alright, but it breaks the column width sync between headers & body:
Sample output when all the words in the first column are colored green with chalk.green('text'):

Should be fixed in 0.7.0. Had to replace standard string handling functions... :)

I still need to add more unit tests to make sure it doesn't break anything when word wrapping or truncating for colouring cases.
