Add Software acknowledgment page

[ecerami]

Fixes cBioPortal/cbioportal#5667

• Added new software acknowledgment page/component.
• Added new property: skin_documentation_software.
• Added new /software router.
• Added link to /software within the footer.

Note: the actual content of the software page is a markdown page, which now exists within the back-end repo, and not part of this PR. See: https://github.com/cBioPortal/cbioportal/blob/master/docs/Software-Acknowledgments.md

Any screenshots or GIFs?

Nice US spelling of acknowledgment

FYI - If we want to allow people to update this config using portal.properties it will also need to be added to config_service.jsp in the backend. We already allow people to override the footer in its entirety, so seems overkill to add it there but just so you know

Looks good to me! Thanks for doing this!

One minor thing is that I personally prefer imperative mood in the subject line:

I find it makes the title more concise and therefore easier to read. Same with PR titles

Opinions about this vary tho

@inodb: Good tip on imperative. So, instead of "Added new route for software page" --> "Add new route for software page"?

Write back! (I think that's imperative :-)

Lol yes 🙂!
