Merging PRs and browser runtime build.

[chr15m]

This PR includes merges for #131 #139 #144 #151.

• Fix false? bug from @theunknownxy
• Several improvements from @robjens
• Fix reply off-by-one error in node repl from @pocka
• Makefile changes to create a distributable browser bundle
• Simplify documentation

See the next PR for updates to the github pages page and distributable minified runtime that people can download and start using immediately.

Would appreciate feedback from anybody interested (@zot @rcarmo ?) before I merge this basically to sanity check I haven't messed anything up.

@Gozala has given me permission to do basic maintenance on this repository and moving forward I would like to proceed in a way that is:

• conservative - not moving too fast or breaking things, mostly bug fixing.
• democratic - community input.

Thanks!

Hello there!

A quick note to say that this is most welcome (in terms of overall approach and ensuring wisp keeps improving). I can't actually test this right now (haven't spent much time on front-end lately) but wanted to encourage you to keep at it, because I think wisp is just too nice to let linger.

Thanks for dropping by @rcarmo and for the support. \o/

I'm going to go ahead and merge this now since there was no dissent. :)
