Fix haddock documentation cross module links

Thsi change fixes the cross module references links.

Fixes #17

Use direct module link to remove the Data.Password prefix

[TristanCacqueray]

This has been produced using this rule @"\([^"]*\)"@ -> @"Data.Password.\1"@

I think it would be better for the reader to change "Bcrypt" into 'Bcrypt', so it links to the data types. This way you don't get superfluous Data.Password. in the introduction text, but still links to the modules.

I'm not familiar with this syntax. Trying @'Data.Password.Bcrypt'@, @'Bcrypt'@ or @Data.Password.'Bcrypt'@ doesn't produce the expected result.
How to get rid of the Data.Password. prefix?

[Vlix]

Ah right, it doesn't automatically link to modules that aren't imported. Can you try with @'Data.Password.Bcrypt.Bcrypt'@? I'm trying to get the text printed in the haddock to be Bcrypt, and link to the data Bcrypt declaration in the Data.Password.Bcrypt module.

[TristanCacqueray]

That seems to work.

This looks good to me.
