openlp.log stays in application data when using custom data folder.

On Windows xp, the debug log file is created in the OpenLP applciation data folder even if a custom data location is used.

I don't not know if this is how it is supposed to work or not, but even if it is, the documentation is incorrect in telling the user to:

"In the Explorer window you left open, navigate up one level into the openlp folder. You will see the openlp.log file." (http://manual.openlp.org/faq.html#id3)
