Move webpage to github pages

[chrjohn]

I'm always frustrated when quickfixj.org is offline.

We should put the content on github pages.

Edit: we should also check the documentation under https://github.com/quickfix-j/quickfixj/tree/master/quickfixj-core/src/main/doc/usermanual whether it is still relevant and/or up-to-date.

Can the user manual and jira also be moved? https://www.quickfixj.org/usermanual/1.5.3/ and https://www.quickfixj.org/jira/browse/ are both inaccessible now

[chrjohn]

Yes that was the intention. I already activated the github issue tracker.

[jgoldrich]

Gotcha. Is there a way to be able to look back at previous tickets?

[chrjohn]

Currently no. We'll have to check how they could be imported here.

While the user manual is not migrated to github pages, can I try to improve the documentation at quickfixj/quickfixj-core/src/main/doc/usermanual ?

As I did this small fix in the README.md, I thought in doing it to on the quickfixj/quickfixj-core/src/main/doc/usermanual/usage/application.html too.
