[amber-docs] RFR: FAQ [v5]

[David Alayachew]

> I'm not married to the format. The hard work, of finding the discussions and linking them inline, has been done. Just want to make sure that we get SOMETHING out there, so that we can have a definitive place to link new folks too when they have questions, for further reading.

David Alayachew has updated the pull request incrementally with five additional commits since the last revision:

 - Update _index.md
   
   Now, we can float FAQ's between the most recent JEP Versions. Less effort for those maintaining things later.
 - Update and rename jep_495_simple_source_files_and_instance_main_methods.md to simple_source_files_and_instance_main_methods.md
   
   If people need to know the JEP, that's easy enough to be able to find out by just looking up the feature name.
 - Update and rename jep_494_module_imports.md to module_imports.md
   
   Yeah, JEP number is not wise.
 - Update jep_494_module_imports.md
   
   Maybe adding the JEP number is unwise.
 - Update jep_495_simple_source_files_and_instance_main_methods.md
   
   Little too LOUD. Of course, this will probably get ripped out, but worth doing anyways, in case the "prototype" becomes the final product lol.
