Wrap the seeds.rb inserts in a transaction so as to speed up importing records (chiefly for devs, I'm assuming).
Previously each insert had its own transaction, which slowed it down a bit.
__Adds loading animation for 'Search by current location' button.__
Sometimes getting a location fix can take several seconds, and before now there was no feedback to the user.
This commit adds a standard gif spinner to that button while we're waiting for a location.
It also adds a 'title' attribute to the button describing what it does, for accessibility purposes.
