Minor change to make compilation easier on OSX 64bit, test cases, eclipse project and launch configs.... Library may work without being pulled.

Recompiled jnilib on OSX 64bit seems to work with only a small change to the native-build.pl script.
Remmoved codesmell from HunspellMain - now Unicode chars are used
Created eclipse project including launch configurations.
Created test cases for Hunspell and Dictionary.
