Update README.md to add missing Requirements section

[manez]

What does this Pull Request do?

Adds the missing Requirements section to bring it in line with the readme template. Took verbiage from the wiki: https://wiki.duraspace.org/display/ISLANDORA/Compound+Solution+Pack

How should this be tested?

Have a look at the changes, verify the links work and that these are the actual requirements. Check against readme template.

Forgot about this for the committers call, but I guess any other @Islandora/7-x-1-x-committers could help with this. JAIL is documented as a requirement but the module itself does not impose it as a requirement (only needed if enabled in the block). I personally vote for consistency across our docs but would also make sure people don't have to install libraries they won't be using. Any thoughts?

at this point I am for including a list of conditional requirements after the requirements and explain which functionality it is a requirement for.
