Fix hex package

[mschae]

Hey,

thanks for releasing 1.0, unfortunately I get the following error when using the hex package:

** (exit) an exception was raised:
    ** (UndefinedFunctionError) undefined function :string_lexer.string/1 (module :string_lexer is not available)
        :string_lexer.string('This is an example')
        lib/earmark/helpers/lookahead_helpers.ex:62: Earmark.Helpers.LookaheadHelpers.tokenize/1
        lib/earmark/helpers/lookahead_helpers.ex:19: Earmark.Helpers.LookaheadHelpers.opens_inline_code/1
        lib/earmark/block.ex:508: Earmark.Block.inline_or_text?/2
        lib/earmark/block.ex:342: Earmark.Block._consolidate_para/3
        lib/earmark/block.ex:148: Earmark.Block._parse/3
        lib/earmark/block.ex:60: Earmark.Block.lines_to_blocks/2
        lib/earmark/block.ex:51: Earmark.Block.parse/2
        lib/earmark.ex:204: Earmark.parse/2
        lib/earmark.ex:186: Earmark.to_html/2

The reason is that the src folder is not included in the hex package. This PR fixes that.

Thanks again

Great catch Michael, sorry to bother you @pragdave but we need a rerelease here. My bad

As a side note, I guess this is the motivation I needed to create the Earsuite project which shall act as kind of an Acceptance Testing Suite for Earmark. Seems https://github.com/philss/floki should do a great job for structural comparison of the created HTLM against a reference.

To close the loop on this, 1.0.1 is published to hex and works fine.

Thanks again everyone!

This is great, I completely s*** up and everybody is thanking me :). Thank you and Dave for cleaning up my mess.

Ha well you forgot to include one measly folder in the package. Tests didn't flag this. If this is your definition of messing up I envy you. ;)

Well thank you for your kind words. I meant it is just great how OSS works, I completely broke Earmark and it took a kind soul a millisecond to fix it.
