Getting the Installation Guide into shippable shape

This includes:
1.) Removing project-specific instructions that are either empty or have
    only instructions saying to install the relevant Karaf feature.
2.) Removing a number of 'infrastructure' features from the user-facing
    Karaf features table.
3.) Adding a URL link to the OpenDaylight software download page
4.) Removing the section referring to the custom distribution downloader

The dominant remaining task is to fill in proper names for features and
short descriptions.
