Upgrade to latest Launch4j version and removed Launch4j code

[taxone]

Hi,
this branch contains two main modifications.

The Launch4j source code is not included any more. Now there's an explict dependency in the pom.xml to the Launch4j artifact (I released it to Maven Central repository). So now it should be easier to manage upgrades to latest Launch4j versions.

The latest Launch4j version (3.4.0) is now used, instead of 3.0.0-pre2.

Commented out?

[taxone]

Yes, because the "workdir" jars are now stored as launch4j artifacts, take a look here:

[lukaszlenart]

Ok, so please remove this section

[taxone]

Done! Thank you for noticing it.

[lukaszlenart]

Looks good, did or do you publish it to Maven Central? I can do it if so

[taxone]

Not yet.
You can do it.

@taxone Please take a look at issue #8 - the workdir jars published to Maven Central are missing the binaries for Linux and OS X, so this pull request breaks the plugin on those platforms.

[taxone]

Thank you so much @strayer!!! I'm going to fix the Linux and Mac jars as soon as possible.

[lukaszlenart]

@taxone let me know and I will publish new version to Maven Central

[taxone]

@lukaszlenart I've just released on Maven Central the Launch workdir jars for Linux and MacOs. Now these jars contain also the "bin" folder and the issue opened by @strayer should be fixed:

Thanks a lot @taxone !
