add support for jvm-opts overrides and environment variables

[BrunoBonacci]

This enables to specify a set of :jvm-opts which will be baked in the executable jar. The options you want to bake into the executable might be different than those ones you use for the development (lein repl). In addition to this it supports environment variables such as $JVM_OPTS which currently aren't in leiningen and it correctly convert to %JVM_OPTS% for windows platform

example:

    :jvm-opts ["-Xmx2g"]
    :bin {:name "foo"
          :jvm-opts ["-server" "$JVM_OPTS" "-Dfile.encoding=utf-8"]}

the output

$ head -3 ./target/foo
:;exec java -server $JVM_OPTS -Dfile.encoding=utf-8 -Dfoo.version=0.5.7 -jar $0 "$@"
@echo off
java -server %JVM_OPTS% -Dfile.encoding=utf-8 -Dfoo.version=0.5.7 -jar %1 "%~f0" %*

Hi, any chance to see this PR merged in any time soon?

[Raynes]

Yep, if you keep complaining at least one more time tomorrow. I'm very complaint oriented. I wait until people are actually frustrated before I merge.

[BrunoBonacci]

[Raynes]

Mostly just because it's 4AM and I desperately need sleep.
