Patch: Speed up NetBeans IDE execution

[Doug Simon]

Your suggestion sounds good. I’ll have to defer to you as to how we generate project configurations to offer those different menu options. I have experience with Eclipse (where saving a file is the only explicit build step I need*).

* in theory - unfortunately Eclipse has its own issues which is only resolved by refreshing a few times.

E.g. have two menu items in project pop-up menu to "Build" and "Build with Dependencies" (I am trying to find out if that is possible). Or do something different on "Build" vs. "Clean and Build" (I know how to do it). Or leave "Clean and Build" action fast. But "Clean" followed by "Build" do the complete build with dependencies (I know how to do it as well).

The ‘mx build’ step will probably take as long NetBeans doing the updating itself but at least it is an explicit step as opposed to occurring each time one edits a file in NetBeans. In Eclipse, this is all somewhat faster given that it does more precise propagation of updates.
