Description of problem:
The page https://fedorahosted.org/spacewalk/wiki/ApiDocs is outdated (v 1.2 1.3 1.4 and 1.5 are missing)
This may lead people to use outdated version of the API because of the lack of documentation
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. go to https://fedorahosted.org/spacewalk/wiki/ApiDocs
API doc listed up to v 1.1
API doc listed up to v 1.5
updated API doc are still accessible by replacing version number in url.
I've put 1.4 and 1.5 there. We did not have 1.2 and 1.3 generated, so I removed the older versions.
