Support Presentation Manager song import

[Jonathan Corwin]

Presentation Manager holds its songs in XML format. We should include an import option for these files.
They have a 30 day demo at http://presentationmanager.com

Songs are in c:\synapx\masterdata\songs.
An example is attached.
Two more example songs are here: http://support.openlp.org/scp/tickets.php?id=2319

Turns out sng files from Presentation Manager (PM) have three different formats:
1) XML, introduced in PM v7 (?), easy to convert
2) proprietary text-based format (PM v6?), somewhat ambiguous
3) plain text (simply verses separated by blank lines)

I have completed a stand-alone script in AHK and used it to convert a user's library of 4600 songs to OpenLyrics.
Next step: port to python and OpenLP import class.

Latest info from creativelifestyles, the producers of PM:

> correct there are two version
>
> tagged xml files
> where the user can define any attributes he likes
>
> or simple text files
> with text files the stuff in { } is ignored
> and spaces indicate new verses

So the "proprietary" format I referred to is actually just treated as plain text by PM. Any author info etc between the {} is ignored, and must originate from elsewhere. This news makes the importer much simpler!
