version 1.0.0 (#78)

* set versions appropriately

* it's true but let's leave it unsaid for now

* start 1.0.0 release notes

* fold the older release notes under another heading to hide them from the main toc

* limit goptions validation to the command, not the mixin

* the mixin won't have a session, make that an argument to get_filter

* fix the type resolution of the build state sieve

* really no reason to have build state be variadic, just test against multiple states

* fedora:28 no longer available from fedora repos

* prune to clear out older layers

* some cleaning functions

* rewording

* just whitespace

* docstring tweaks

* we need some archive tests

* make the filtering function names more obvious

* unused import

* hush coverage

* copyright years

* reflect renamed functions

* reflect renamed functions

* saw some issues with the unused source repos, so let's disable them

* unit tests and cleanup for archives

* comments to explain

* let's do this
