* add a redirect block to the top if it doesn't already exist, even if there's an existing redirect
* fix obj tests
* remove active parameter
* update tests
* add back spaces
* move imports
* remove unused code
* create_new_vhost_from_default --> duplicate_vhost
* add source_path property
* set source path for duplicated vhost
* change around logic of where making ssl happens

* flip connected pointer direction for finding newly made server block to match previous redirect search constraints
* also test for new redirect block styles
* fix contains_list and test redirect blocks
* update lint, parser, and obj tests
* reset new vhost (fixing previous bug) and move removing default from addrs under if statement
* reuse and update newly created ssl server block when appropriate, and update unit tests
* append newly created server blocks to file instead of inserting directly after, so we don't have to update other vhosts' paths
* add coverage for NO_IF_REDIRECT_COMMENT_BLOCK
* add coverage for parser load calls
* replace some double quotes with single quotes
* replace backslash continuations with parentheses
* update docstrings
* switch to only creating a new block on redirect enhancement, including removing the get_vhosts cache

* Save path to vhost in file while parsing in get_vhosts().
* Disable creating a new server block when no names match.
* Make parser select vhost based on information in the vhost it found previously, rather than searching again for a match.
