Fix () [] were rendered as links when not in link 2

Highlight angle braced hyperlinks.

Remove outdated fields from syntax header.

Improve bold and italic tests.

Use a single code block style on README.

Respect global fold config

Deleted overriding global fold configuration for markdown buffers and
improved README on purpose of vim_markdown_folding_disabled.

were not being highlighted on top level.

Support YAML frontmatter headers v2.

Remove useless line in Toc funciton.

Add LateX $ and $$ math support.

Fix parenthesis () and square brackets [] that were rendered as links when not in link.

Add unit tests and travis support.

Toc: Pass errors if no atx headers are processed.

Automatically continue blockquote on line break

This is accomplished by treating `>` as a comment marker.

1. Fix not only *+- but also \ matched

Need not escape inside [] because backslash codes do not work inside [].
So pattern [\*+-] match also \.

2. Fix not only list but also horizontal are indented

If only space and three '*' or '-' character are in the line,
this line means horizontal item.
If current line is below horizontal item, it need not to indent.
Following example is horizontal item.

---
***
- - -
* * *

And list item must be specified space after [*-+].
Following example is list item.
* foo
- bar
+ baz

But following example is not list item.
*foo
-bar
+baz

Add indent test file for above bugs.

Fix #90

:Toc causes errors because getqflist() returns empty for location
list.

Fix #100.

Add Setex examples to the multiple headers test.

Fixes issue #102

Changing Vundle "Bundle" references to "Plugin"

Add commands to increase and decrease header levels.

Vundle is changing their interface from `Bundle*` to `Plugin*`.
See 
https://github.com/gmarik/Vundle.vim/blob/v0.10.2/doc/vundle.txt#L372-L396 for more information on this.

Make the default mappings 'buffer local'

If mappings aren't defined as 'buffer local', they are defined in other
files too and this causes conflicts with mappings there.

Fix folding bug if folding disabled option is 0

Don't allow spaces before headers in nav mappings.

Breaks too often when you have code blocks with comments that start with #.
