Use Huffman algorithm for hints generation (fix #112)

The Huffman algorithm is now used to generate optimal prefix codes for all
focusable elements. The area of each element is used as _weight_. The
higher the weight, the shorter the hint.

Note:

The old algorithm seemed to give shorter hints to `<a>` elements. That is
currently not the case with the new algorithm.

Other related changes:

- Change minimum allowed number of hint chars from 3 to 2, since the new
  algorithm supports it.
- Change default hint chars, since with the new algorithm the best keys
  should be at the beginning of the string.
- My editor is set to strip trailing white space. Apparently there was a
  lot of trailing whitespace in many files, so a diff of this commit is a
  bit messy.
Fix frames handling

Every frame got the same hints as the others, basically. Now
`Marker.createMarkers()` does not give its markers any hints anymore.
Instead, all markers from all frames are collected in `injectHints()` and
then given markers. I am not sure how good/nice the solution is, but it
works.
Updated Polish translation
Added missing parenthesis

Note that even functions whose last argument is a one-line function
literal have parenthesis now.

How to do with functions whose last argument is a multi-line function is
not settled yet. Neither is whether `require` should have parenthesis.
