Use --help to check if java is the right version (like the launcher), rather than just running the installer and moaning if it exits with non 0.
Fixes issue 1479

Rather than using an include to modify the path when the main installer resumes, create a symlink to the newly installed java binary and use that

Lotsa changes to the linux installer to make it also run on OpenSolaris (and possibly normal solaris aswell, I don't have gui access to a normal solaris machine from here will try when I go back to uni)
Rather than building a separate installer.jar that contains a subset of DMDirc.jar, just use java -cp DMDirc.jar com.dmdirc.installer.Main like we should have done all along really.
Linux scripts now use kdialog/zenity where appropriate to show error messages. No longer expect users to have a terminal open
