Update dependencies: prepend-http and CSVparse

I've node v0.10.33 running using nvm on a OSX 10.10.1 machine and after installing it globally via `npm install -g tmi` I kept on getting this error.

```
vagrant@precise32:~$ npm install -g tmi

After digging a bit I found that the modules `prepend-http` and `csv-parse` were listed as dev dependencies and weren't getting installed without manually running `npm install` in the module directory.

Just to be sure I created a clean new vagrant box (precise32) and installed nvm, node v0.10.33 and tmi and still got the same error.  
I've moved them to dependencies hash now.
