Adds a "requirements.txt" to the project. This will not be used during a
standard installation however will be used to indicate which are known
working packages in cases of conflicts.
Update README and documentaion to reflect this.
Update the instructions for installing WA from git not to use
pip as this method does not process dependency_links correctly and
results in an incompatible version of devlib being installed.
Restructure the documentation to be split into `User Information` and
`Developer Information`, and split the how to guides into their
corresponding section.
