Update README

1) Give an exact link to https://www.unrealircd.org/docs/UnrealIRCd_releases
which describes the supported versions and EOL stuff in more detail.
2) Make clear that we have better instructions on the wiki with regards to installation
and that users should use that one instead (the ones in the README are really meant as fall-back)
3) Some nicer formatting here and there (minor)
