Create AddNodes() in database.go
Add import utilities

Ref #62
Merge branch 'f.import' into development
Added a search bar

Closes #29
Simplify root handler

This will not yet be functional, but will be patched up in coming
commits.

Ref #106
Clean up the res/ directory structure

This will allow files to be served directly using a normal HTTP server,
rather than requiring complex multiplexing.

Ref #106
Update links in res/web/

This will make the new directory structure usable. All requests other
than to /api/ and /captcha/ could now be handled by another HTTP server,
such as nginx or lighttpd.

Close #106
Merge branch 'f.better-http-handling' into development
Add minimal frontend support for search
Merge remote-tracking branch 'origin/f.js-search' into development

Conflicts:
	res/web/index.html.tmpl
Add ExtraVerificationFlags

This will allow slight customization of verification commands. It would
mainly be for networks that require verification via the network itself,
via the new node's own IP address, and so would require a -6 or similar
option.

Close #93
Implement admin addresses that do not require auth

Close #110
Unescape map attribution to allow links

Close #112
Add /node/ handler
