[sword-devel] Added new function to the Sword library: SWMgr::Version()

[Joachim Ansorg]

Hi!

I added the function "const float SWMgr::Version() const" because modules 
have now the tag MinimumVersion so getting the used version should be 
possible.

But I noticed that the BHS module uses "1.5.2" in the MinimumVersion tag, but 
this is not a float. Troy & Chris, is it possible to change the 
MinimumVersion tag content to a float like value (1.52)? I'd be glad for 
this, float is the most fitting data type IMHO.

Thank you!
Joachim
