Option to include hidden files in export.

It would be nice to have the option to include hidden files in the export. For example, I always forget that I need to recreate a .bowerrc file when I create a new project with my custom profile.

+1 for this. A lot of those node based frontend fancy tools add some .file configs, which devs want to include in the profiles.

@ryancramerdesign , this is an important issue. The exclusion on filenames starting with dots also affects a lot of modules.

It would be cool to have an option to include / exclude everything you want, to override the defaults by regular expression mask or something like this. This would solve not only this issue, but a few similar (#13, #7).
