using delete as HTTP method name in routeConfig crashes the process

[Thesephi]

Consider the following routeConfig:

{
  'delete /item/:id' : handler
}

Expected: the route gets registered and the framework behaves as such
Actual: the whole process is crashed with a cryptic error message:

TypeError: c[i] is not a function

Reason is that the underlying restify server only recognizes del as the method name, not delete. This happens also when there's a capitalization mismatch (e.g. Get vs get or PUT vs put). We'll probably want to normalize all verbs before feeding to restify.

Related: using an invalid route signature such as /some-path (no method name before) as opposed to get /some-path also crashes the process with a cryptic error message. We probably wanna throw a user-understandable error instead.

Related: using an invalid route signature such as /get some-path (the slash is put before the verb instead of before the path) also crashes the process. Again, a nicely formatted error / warning message would be awesome.
