remove buffertools dependency

nginxparser only use buffertool to concat buffers, which is doable with
the native `Buffer` class since v0.7.11. Removing buffertools make the
installation easier and quicker (no need to compile buffertools)

Version of buffertools package has been updated

fix bad regular expression error.

fix bad regular expression error.
\\[ to \[

replace [] into [-] while parse line

for better perfermance

fix two bugs;
1: while the log variable in  square brackets,like
[$remote_addr] parser will throw Invalid regular expression;
2: when then variable is null ,this whole piece of log will parse to
null

Correcting typo in package name

Require name is "nginxparser" it failed with "nginx_parser"

Buffertools patches the Buffer class from C++, so even though
it isn't used in index.js, it's still necessary.
