Favorites URLs are incorrect now

```
Hi there;
i try to use favoriteCreate function and i find it not working and it give this
message:"{"errors":[{"message":"Sorry, that page does not exist","code":34}]}"
i check twitcurlurls.h file to find what the problem and i find that Favorites
URLs are written incorrect way
const std::string TWITCURL_FAVORITECREATE_URL = TWITCURL_BASE_URL +
"favorites/create/";
like Status URLs:
const std::string TWITCURL_RETWEET_URL = TWITCURL_BASE_URL +
"statuses/retweet/";
but twitter change the syntax to like this:
https://api.twitter.com/1.1/favorites/create.json?id=243138128959913986
rather than:
https://api.twitter.com/1.1/favorites/create/241259202004267009.json

i am using last version from Github with Ubuntu server 15.04

thanks.

```

Open twitcurlurls.h and inspect TWITCURL_FAVORITECREATE_URL alongside the status URL constants. Update the favorite-create request to match the Twitter API URL form shown in the report, then exercise favoriteCreate and verify it no longer returns the page-does-not-exist response.
