Space oddities in .java code generated by preprocessor

[benfry]

A few oddities in the generated code from the preprocessor that should be easy to fix. @sampottinger You mentioned you might look at preproc things today, I'm hoping these might be quick?

• There's an extra space character added before functions (perhaps only functions where public has been added? not sure).
• Several extra blank lines of text appear toward the top of the file (after imports and before public class iirc)
• None of the rest of the code is indented at all: i.e. once the sketch is wrapped in public class Blah extends PApplet, the inner lines have no indent.

I'd also like to rewrite the “exported at” text, but can take care of that.

Closing as resolved with #609.
