- allow converting from one database to another, no need for tables to be in one database anylonger (this also allows switching from one DBMS that was used with phpBB2 to another DBMS supported by phpBB3 including new systems available in Olympus only)

Browse Source 
- abstracted some installation code that is now relevant to converting as well into functions_install.php (mostly DBMS selection related)
- fixed a weird smiley path problem, no idea why nobody else noticed this, maybe my fix was incorrect?
- forgot to commit a file last time
