3c69bc8f48 re-export ‘(<|>)’, ‘many’, ‘some’, and ‘optional’, fixes #9 
These functions are now re-exported from ‘Control.Applicative’
module. ‘many’ and ‘some’ are now part of ‘Alternative’ instance of
‘ParsecT’.

Note that these functions are re-exported only in ‘Text.MegaParsec’
module, but not in ‘Text.MegaParsec.Prim’ to avoid duplication of
floating doc-strings. Others internal modules now just casually import
‘Control.Applicative’ for their needs.

Note that ‘many1’ was renamed to ‘some’, the same is done for other
parsers that had ‘many1’ part in their names (for consistency).

189106f001 Remove try in float parser. 
According to this post
(http://blog.ezyang.com/2014/05/parsec-try-a-or-b-considered-harmful/),
the error message could be confusing if using `try`. `"3.a"` is one case
to expose this behavior.

c5bcdfb220 rewritten parsing of numbers, fixes #2 and #3 
Changed how numbers are parsed because they were parsed in a naïf and
hairy way. Added tests for #2 and #3 (in old Parsec project these are
number 35 and 39 respectively).

* Since Haskell report doesn't say anything about sign, I've made
  ‘integer’ and ‘float’ parse numbers without sign.

* Removed ‘natural’ parser, it's equal to new ‘integer’ now.

* Renamed ‘naturalOrFloat’ → ‘number’ — this doesn't parse sign too.

* Added new combinator ‘signed’ to parse all sorts of signed numbers.

* For the sake of convenience I've added ‘integer'’, ‘float'’, and
 ‘number'’ combinators that also can parse signed numbers out of box.

860764939c Track current position in the 'tokens' function 
Example

Before:

  Prelude Text.Parsec> parseTest (string "abcd") "abbe"
  parse error at (line 1, column 1):
  unexpected "b"
  expecting "abcd"

After:

  *Main> parseTest (string "abcd") "abbe"
  parse error at (line 1, column 3):
  unexpected "b"
  expecting "cd"

Before this patch, 'b' was reported to be found at 1:1, which is clearly not the
case. After this patch, we correctly report the location of the wrong token, and
also report missing tokens starting from that position.

b8990ab042 When merging error messages, prefer known messages to unknown ones 
This fixes a regression introduced by:

Sun Feb 20 18:24:22 EET 2011  Roman Cheplyaka <roma@ro-che.info>
  * Choose the longest match when merging error messages

The source of the regression is that parsec sometimes generates dummy (aka
"unknown") error messages when no actual error has occurred.

So, when merging errors, before simply looking at the positions we should check
if one of them is unknown and just ignore it.

Reported by Matthias Hörmann.
