upgrade to latest bloop launcher

[ArturGajowy]

The install script outputs some WARN and some stacktrace on my machine (see below).
Otherwise the instalation seems to work.
Same thing happens if I run sh fury-0.3.0.sh instead of bash fury-0.3.0.sh.

artur@y510p:~$ bash fury-0.3.0.sh

artur@y510p:~$ 

[mzarnowski]

It should be fixed with new version of launcher: (scalacenter/bloop#798)

[propensive]

Let's upgrade this. Seeing the stack trace isn't particularly great, either - I hope that's fixed in the new launcher, too.
