replace update sites' index.html w/ more useful information about how to install, quality of release, etc.

(2009-04-27 12:38:57) nickboldt: the html in the update site is entirely irrelevant and could be replaced w/ a pointer back to the install instructions

(2009-04-27 12:39:24) nickboldt: I doubt anyone ever uses it to download individual feature jars, so it's kinda misleading

(2009-04-27 12:39:53) nickboldt: for me the only value it provides is seeing the build timestamp and hudson ID so I know how recent it is

(2009-04-27 12:42:37) |xam_at_hibernat: nickboldt: for the updatesite index.html then I agree - the actually listing of files with links is pointless for download; BUT having the page showing this is the url for Development|Stable|Nightly and that you can use this by adding the updatesite to eclipse and alternatively download the zips directly from <point to links > and here are some more info <point to the install docs>

See also https://jira.jboss.org/jira/browse/JBIDE-4033, which can be done in parallel to this task.
