Closes #2.

Merge pull request #1 from vitalk/fenced-block-configuration

Add support of custom fenced block per filetype, and allow to refine existing
rules via `vimrc`.

The `g:fancy_filetypes` has the following format:

```vim
let g:fancy_filetypes = {
    \ 'filetype_a': [format_a, format_b],
    \ 'filetype_b': [format_c],
    \ }

let format_a = {
    \ 'start_at': start_of_the_block_regexp,
    \ 'end_at':   end_of_the_block_regexp,
    \ 'filetype': function_to_detect_filetype,
    \ }

fun! function_to_detect_filetype(fancy)
    return 'my_format'
endf
```

Note, that `function_to_detect_filetype` has access to `fancy` object.

Typo in error message

Shorten and more fancy name for repository
