Change section headers to be less prominent

[skorokithakis]

I have changed the section headers from an h3 to just bold, as I think there is too much visual clutter in the Markdown template, as most elements are headers. This way looks a bit better rendered.

hmm, thanks for your interest. I'm not inclined into integrating such change in gitchangelog because it seems you are changing semantic marks to tinker presentation issues. This is clearly a section title and I don't feel it is the right solution to mark it as important (the semantics of double star inclosure) in a lone paragraph.

It might be beautiful in your current theme, but won't probably in other theme... additionally this makes the generated changelog to loose readibility both in ASCII and by machines : for instance, automatic links to section are not anymore possible (and inclusion in table of contents).

I hope you understand my concerns.

In an other hand, I could consider favorably a request to tune down the semantic importance of these sections and use for instance a definition list... but this will need to be thought through and is probably not of primary concern.

Of course, this type of modification is perfectly understandable on your personal level to suit your particular needs and should be encouraged. I feel that it is still not yet enough streamlined.

If you don't mind, I'm happy to keep this PR open as I definitively want to come back later to check out these 2 alternatives I've just mentioned (changing the semantic level of sections and ensure that personal modification to template are streamlined). But don't expect your PR to be included as-is, nor me checking back this soon.

Sure, that's fine, thanks. The underlying problem that made me come here is that I can't easily change the template myself. It would be great if I could just include the template in the config file as a string (to avoid creating new files), but that's currently not possible (and I don't think it's possible to use any other template at all?).
