#30 Fix nested package generation

[David]

Fix code generation of nested packages for java,php and as3

Also fix an uninitialized variable bug in the php generator,
and fix a bug, where the package of an as3 class was incorrectly
written if the package was a nested package: the top level package
name was written, followed by the open curly brace and after the
brace, the other package name parts were written.

Vincent, I believe you already fixed this type of problem in the dia2code-c++ branch?
I would consider merging the branch to the master. What do you think?

[Oliver Kellogg]

I went ahead and created an initial development release from the dia2code-c++ branch.
The plan is to direct what little time I have to this branch.
It would help if you could try out the new Java generation, in particular whether it solves the nested package problem that you observed. Many thanks.

The dia2copde-c++ branch fixes the issue, but behaves different than master with this patch applied. If you have a package named "net.sourceforge.dia" and a nested package "codegen", the master branch would create the directory structure "net/sourceforge/dia/codegen" for any class in package "net.sourceforge.dia.codegen". The dia2code-c++ branch would create this directory structure: "net.sourceforge.dia/codegen".
I'm not sure which behaviour is more correct. Personally i like the behaviour of master more.

I have addressed this in commit 2531d3.
