Auto update travis

[AngelikaZa]

1. Automatic build of any updates on the master branch via travis working on local fork.

• For deployment on the main repo need to add the repo's token as the GITHUB_TOKEN variable on the TravisCI.com settings as an environment variable (needs admin access).

2. Removing the --frail option from remark allows build to happen even in the presence of broken links.

3. Broken links updated and typos in the neuroimaging software page fixed.

Resolves #99 and much of #51

Implemented the "problems" of #102 here.

@r03ert0 @katjaq I don't have admin access to the travis settings for this repo: I suspect one of you might. Could you link into this? ❤️

Will approve this and merge now.

I think I did set up travis correctly, so this should work.

🤞
