better compatibility for upcoming Trinidad 1.5
update version to next development snapshot
allow to change jsvc's -wait and jruby's shell from env + keep stdin as is by default
allow to configure jsvc's -wait and -keepstdin in generated init.d script
decrease default stack-size 1536k should be still a very 'pessimistic' guess
refactor log_file to out_file ... as it might be confusing it's where OUT gets redirected !
do not ask for ruby compat version - simply use the current one
travis-up
more strict development dependency constraints
allow to specify gem trinidad's version to be used
refactor init.d script - make sure -cwd $BASE_DIR happens + warn on missing base path
