Fix error in touchcancel

Please see single commit https://github.com/Philzen/jQ.Mobi-Highcharts/commit/2639980fb7eea7dc51bd19a8c2484dfcc1855a02 or apply patch as below

There's a simple typo:
```
2428  -            cleaRtimeout(longTapTimer);
2428  +            clearTimeout(longTapTimer);
```
Pls disregard the other stuff, that's just my sandbox files.
Couldn't see a way to open an issue or opening a pull request for only this particular commit, but i hope it helps :)
