QJniEnvironment: extend API

This patch adds some convenience methods to QJniEnvironment API:
* an overload of registerNativeMethods() that accepts jclass instead
  of const char *className.
* a findMethod() function is added to query a methodID of a static
  or nonstatic method by its name and signature.
