Add support for coloured panels

[chrisjaimon2012]

Github markdown added a feature to support highlighting (note and warning) using blockquotes

Note
This is a note

Warning
This is a warning

Can we add the support for this to be automatically converted to the coloured panels on Confluence.
Right now we can do this using macros, like

<!-- Macro: :box:([^:]+):([^:]*):(.+):
     Template: ac:box
     Icon: true
     Name: ${1}
     Title: ${2}
     Body: ${3} -->

:box:info::Foobar:
:box:tip:Tip of day:Foobar:
:box:note::Foobar:
:box:warning:Alert!:Foobar:

But would be nice to have blockquotes, converted to coloured panels on confluence without using the macros.

It's possible with my inline Macros like so:

<!-- Macro: >\s\*\*Note\*\*
     Template: #inline
     inline: |
          > <span style="color: blue;">**ⓘ Note**</span>
     -->
<!-- Macro: >\s\*\*Warning\*\*
     Template: #inline
     inline: |
          > <span style="color: red;">**⚠ Warning**</span>
     -->

> **Note**
> sdfasdf
> asdfasdf

> **Warning**
> asdfasdf
> asdfasdf
> asdfasdf

If you do not have inline Macros, you need to have two files:

note.md

> <span style="color: blue;">**ⓘ Note**</span>

warning.md

> <span style="color: red;">**⚠ Warning**</span>

and these macros:

<!-- Macro: >\s\*\*Note\*\*
     Template: note.md
     -->
<!-- Macro: >\s\*\*Warning\*\*
     Template: warning.md
     -->

> **Note**
> sdfasdf
> asdfasdf

> **Warning**
> asdfasdf
> asdfasdf
> asdfasdf
