Add configuration option to allow more file types in the _media directory

[caendesilva]

As Hyde strives to be safe by default, currently the glob pattern for _media file transfers is set to "safe" files. However, it would be nice to have the config option to expand on this.

Implemented. You can now specify comma separated values in the config.

Here are the defaults:

config('hyde.media_extensions', 'png,svg,jpg,jpeg,gif,ico,css,js'))

Here is how the glob pattern is now loaded in the CollectionService for reference:

return glob(Hyde::path('_media/*.{'.str_replace(' ', '',
    config('hyde.media_extensions', 'png,svg,jpg,jpeg,gif,ico,css,js')).'}'), GLOB_BRACE
);
