Get rid of hyphenation

What hyphenation does is break up words (with a hyphen) that are known
to the dictionary and are about to go out of the container.
E.g.

|This is some text and my con-|
|tainer ends where I added the|
|pipe                         |

Hypenation will split up all words near the end of the container length.
I would prefer to actually have it like this, though - without hyphens:
|This is some text and my     |
|container end where I added  |
|the pipe                     |

I don't think it makes sense to break up every possible word that can
be broken up; I think we only need to break up words that, in their
entirety are too long for the container, like:

|longwordlongwordlongwordlongw|
|ordlongword                  |

Yes, this will not have hyphentation, but to be fair, words over 800px
are probably not words that would be in the dictionary and would get
hyphenation. So in that case it doesn't really add much to have the
hyphenation.
