updating default chai style to be consistent with docs

According to http://chaijs.com/, assert and expect shouldn't be called as a function. This was breaking my initial Teaspoon installation. I also updated https://github.com/modeset/teaspoon/wiki/Quick-Start-Walkthrough to reflect updated chai expect syntax. Hope that helps!

Allow customizable asset path normalization.

We are using a custom extension which passes through a pre-processor (in
our case converting ES6 module semantics with AMD output), and need to
instruct Teaspoon to use the correct extension on the served files.

Removes thread check as the thread may be dead

Depending on the rack_options passed into Rack::Server the thread may
not stay running and can simply exit immediately. If that happens then
this will always return false. I doesn't seem to be necessary to check
the thread status before checking if the server is running via TCP so
I've removed this check.
