Change string::split once more

Browse Source 
- Delimiters now end up in their own token when keepSeparators is true.
- When ignoreEmptyTokens is false we now add a token at the end when the last character is a delimiter.
While this means some changes, the ignoreEmptyTokens=false didn't work correct in 1.8 anyway, so another change shouldn't break much.
Thanks @manni63 for bringing this up in forum: http://irrlicht.sourceforge.net/forum/viewtopic.php?f=7&t=51584&p=299634#p299634
