Add more API methods to get server's tick times

[molor]

Is your feature request related to a problem?

Yes. Currently there's no method in API to get NMS tickTimes10s and tickTimes60s
Server#getTickTimes returns only tickTimes5s.

Describe the solution you'd like.

Deprecate Server#getTickTimes() and instead add methods like getTickTimes5s(), getTickTimes10s() and getTickTimes60s().

Describe alternatives you've considered.

Add Server#getMSPT() (just copy the logic from mspt command and return same double array).

Currently I'm getting these values using Reflection API, and it's very inconvenient...
