Cpsk datematch

* Plugin is now able to also match date when user specifies it in query. For instance `10.12.2014 bus z TO do BA`
* Also added more examples
* Don't throw exception when there are no results, rather return "Nothing found"

This closes #29 
@Adman if I am reading this correctly for 

`bus z to do ba 127.0.0.1`

would make `f='to'`, `t='ba'`, `time='127.0.0.1'`. Thus, the time would be just wrong and moreover, this should be date, not time.
