Add configurable option for the temp build directory

Using this command line:

$ electron-packager . UF --platform=win32 --overwrite --arch=ia32 --version=0.34.2

My app builds just fine if I executed on a subset of it (e.g. 2 of 41 chapters of an educational resource).

However, a full build fails silently (20G of product, most of that videos).

Nervous about shipping product in 2 weeks… so close to working!

How do I debug this?

Oh, beautiful.

electron-packager uses os.tmpdir() which, if I look at /usr/lib/nodejs/os.js I can see is:

exports.tmpdir = function() {
  return process.env.TMPDIR ||
         process.env.TMP ||
         process.env.TEMP ||
         (process.platform === 'win32' ? 'c:\\windows\\temp' : '/tmp');
};

So all I need to do is set TMPDIR (or TMP or TEMP) in my shell’s environment before calling node-packager. Long live open source!

@malept The problem is that is global, so all parallel builds will end up using the last set value. I should have a pull request soon that adds the configurable switch. Just testing it out now.
