Update quickbook version number.

svn path=/branches/quickbook-1.5/; revision=53447
Create entry for 1.5 in the change log.

Starting it of with some of the changes that have been made to quickbook
since 1.4 - considering the first 1.4 release as the proper 1.4 release.

svn path=/branches/quickbook-1.5/; revision=53448
Wrap the template info in a struct.

So that I can add extra scoping info.

svn path=/branches/quickbook-1.5/; revision=53449

svn path=/branches/quickbook-1.5/; revision=53452

svn path=/branches/quickbook-1.5/; revision=53453
Teletype source mode. Refs #1202.

svn path=/branches/quickbook-1.5/; revision=53454
Make sure that a template expansion ends with a ']'.

{{{
[template foo 1]
[fool]
}}}

was generating `1[fool]` - the template would be expanded but then when it
didn't match the `]` it would fail and just get copied to the output. This
change checks for `]` before expanding the template. So it now generates
`[fool]` which is an improvement.

I'm not including a version switch as I see this as a plain bug fix - I can't
imagine this change ever being anything but beneficial.
