Custom allbullet setting

[SmileyChris]

It provides a new all_bullets setting per category type that can override the global default.
This is useful if you want to have a text-only section (for example, an text introduction to the release)

Implementation Details

• Updated fragment types loading system to support new features
• Modified templates to handle new all_bullets configuration
• Added tests for new functionality
• Updated documentation to explain new features

Thanks for the PR.

This is something that I was also looking to have in towncrier.

I was thinking to have someting like 123.highlight.rst

The higlight is a special type that is rendered first and without a heading.

description make me think like this is the only / single description for a release.

With highlight you can have multiple highlights for the release.
The highlights can still be associated with an issue.

This can be currently implemented with a custom template... but maybe we can have a good default

[SmileyChris]

Sure, highlight might be a better name.

This PR actually makes the existing default template respect the exsiting all_bullets setting as well, so that's a plus :)
Another small feature it adds is the ability to extend the built-in types with a custom one without having to write them all out (as shown in the docs example).

@adiroiban so at the moment, this just provides individuals to add this highlight section.

Should we just add it as a default since it's kind-of a useful thing and having a standard for it is better than people having to do it themselves?

I think that it makes sense to have this available as default and with associated documentation.

@SmileyChris do you think that you will have time to work on this in the next few days?

I am planning to do a new release... and just wanted to see if I should wait for this PR.

No hurry.

Cheers
