Fixed post meetup button position (was too close to other elements, especially on iphone).

Moved Learn More button away from section above on mobiles.
Added command to test jekyll build on local area network in _config_dev.yml - useful to confirm all works on various devices (chrome dev tools sometimes fail).
Added logic to change link under "Learn More" button in Upcoming Events to meetup link if no dedicated page for upcoming event present (which should mostly be the case).
