Issue installing on OS X Mavericks

[austinhyde]

I'm not sure if this occurs on other versions of OS X, but at least on Mavericks, I got the following error while installing:

$ npm install irc

I was able to resolve these errors by

• Installing the full XCode app (not just the command line tools), and running it once to accept the EULA
• brew install icu4c
• ln -s /usr/local/Cellar/icu4c/54.1/include/* /usr/local/include/
• npm install irc again

Someone familiar with the involved tools/dependencies should verify this is the correct solution, and the install documentation should be updated.

It actually installed, as you can see (the [email protected] node_modules/irc bit means it installed). The README specifies that there are optional dependencies that should be installed.

To be clear, iconv and node-icu-charset-detector are optional dependencies. This is specified in the README, and I've made it clearer.
