Non-source files aren't copied over unless an `--include` pattern is added

[mstade]

By default, ez-build should copy over any non-source file, i.e. anything outside of the --include and --exclude sets. Currently, the only way to make ez-build copy files over is by explicitly adding them as included files via --include.

Steps to reproduce:

1. Make a new project with the following structure:

   src/
    source.js
    not-source.txt

   It doesn't matter what source.js contains, so long as it's valid and will compile. not-source.txt can be empty or have content, it doesn't matter.

2. Run ez-build

   Expected results:

The lib directory should look like so:

lib/
  source.js
  source.js.map
  non-source.txt

Actual results

Only the source files are included:

lib/
  source.js
  source.js.map

Workaround

Add --include patterns for any files that should be included in the output directory. For example, to include all css files in the build:

$ ez-build --include "**/*.css"

The quotes are probably necessary so the shell doesn't expand the glob.
