tree-edit command does not work on Linux

[ghost]

The tree-edit command when used from the server console attempts to use "javaw". As far as I'm aware, Java on Linux just uses "java". As such, the tree-edit command does not work and the plugin is unusable without changes. This affects both versions 1.1 and 2.0.0-alpha6.

I was able to fix it by making a symlink from javaw to java in /bin, but the actual fix would be to adjust edit-tree to use "java" instead of "javaw".
