feat($state): added 'state' to state reload method (feat no.1612)

[maoryosef]

• modiefied options.reload parameter in transitionTo method to accept the
  following:
  {reload : true} will reload all states
  {reload : 'foo.bar'} will reload foo.bar, and any children
  {reload : stateObj} will reload state found in stateObj, and any
  children.
• added 'state' parameter(string|object) to $state.reload method,
  to be passed to $state.transitionTo method as the reload option.
• test the $state.reload with state parameter

Thanks, really appreciate the work.

If @nateabele approves of this API change, I'll want to merge this in manually, tweaking lines 1002-1020 to closer match the ui-router coding style.

[christopherthielen]

The block above should be something closer to:

var reloadState = options.reload === true ? fromPath[0] : findState(options.state);
 if (options.reload && !reloadState) {
          throw new Error("No such reload state '" + options.reload + "'");
        }
var skipTriggerReloadCheck = !!reloadState;
        while (state && state === fromPath[keep] && state !== reloadState) {
          locals = toLocals[keep] = state.locals;
          keep++;
          state = toPath[keep];
        }

@christopherthielen Do you want this fixed before we merge?

[nateabele]

Or, wait looks like it was already fixed?

[christopherthielen]

yeah, they already made the changes I asked for

[oriweingart]

Done, refactor the code according to your comment.

[nateabele]

👍 Just squash the commits.

Good work people. @nateabele , someone should add this in the documentation, it took me half a day looking into workarounds for this problem only to find that its solved already, just not mentioned in the documentation. (This is a common problem apparently and people are using some scary workarounds)

@lefterisk Go for it. 😄

@nateabele created pull request #2347 for this :)

I'm not sure if I understand this right, but the reload string must be an absolute state name? I want to pass a relative state path like '.child'. I think it would be more straightforward.
