Load plugin and theme classes after user privs

Check current_user_can before loading plugin and theme classes to keep load time minimum on non-privileged users.
move loading API classes into init method

Preliminary step while I figure out if spl_autoload_register is worthwhile for loading classes.
add method autoload and spl_autoload_register
bump
cleanup autoload code and add markdown.php loading
fix markdown loading for autoload
switched rendering to erusev/parsedown

https://github.com/erusev/parsedown
working on header parsing
get remote file, parse and store headers

eliminate unused methods and adjust for saving remote branch and remote version.

Hopefully saving only remote file headers in transients will speed up database queries.
Merge branch 'parse-headers' into develop
bump
temporary fix for changing $response

 from stdClass to array
strpos faster than strstr
set branch to 'master' if not already set
spacing and minor doc fixes
allow for CHANGES.md or CHANGELOG.md

Now check for either of these files as a changelog.
better method of checking for different

named changelogs
bump
Create composer.json
Update README.md
