Idea to enhance the library. Add .nomedia method

[denebchorny]

Hi sir,

One of the most common thing developing android apps that use camera or external directory is to use a ".nomedia" file to hide files from explorer.

You can eassily add a method to EasyImageConfiguration class that create this .nomedia file in the especified directory. Somthing like:

EasyImage.configuration(context) .setImagesFolderName("directory") .hideFilesFromDirectory(true).

It could be very useful.

Tell me if this is a good idea.

Have a nice day and thanks for your lib.
