Added support for passing in replace-in-file functions

[Borduhh]

Added the ability to pass in a function as supported by replace-in-file(https://github.com/adamreisnz/replace-in-file#using-callbacks-for-to).

This is helpful when you are updating versioning for non-standard release channels like Android (what we are using it for).

 {
    files: ['app.config.js'],
    from: 'versionCode: .*',
    to: (match) => `versionCode: ${parseInt(match.split(':')[1].trim()) + 1}`,
 },

closes #45
