Installer: update 'EULA' window

* De-escalate the severety of data loss from "high risk" to "risk".

* Remove the advice to not create partitions with DriveSetup. It's been tested
  and been working well since the last alpha. Do recommend making backups of
  all partitions.

* Remove description how to add Haiku to Grub. It's too much detail and the
  user would have to memorize the info. Add a link to our Booting guide
  instead.

* Mention BootManager as an alternative to boot Haiku, refering to the
  Userguide for more info.

* Alpha -> Beta

* Only give normal thanks instead of "a lot" and don't beg to like us.
  Sounded a bit desperate...
