Incorrect variable declaration in strict mode

[Ilrilan]

Error in file requireg/lib/requireg.js

...
function resolve(module, dirname) {
  var i, resolver, modulePath

  for (i = 0, l = resolvers.length; i < l; i += 1) {
    resolver = resolvers[i]
   ...

In strict mode variable l must be declared before use:

  var i, l, resolver, modulePath

Can you provide a PR for the fix? Thank you!
