Issue #254 Slight change of build steps. Remove unused links from install.rst.
Issue #234 Fix link from API to "standard/fhs" web page.
Remove accidentally committed .autosave files possibly created by QtCreator and ignore them in the future.
Issue #254 Change links in documentation to point to new web pages hosted on GitHub.

Unfortunately, these links are all "hard-coded" at the moment and must always be edited manually whenever the web site is moved to another location.
