Log:
[SNDVOL32]
- Implement loading of resources and parsing the dialog template in memory
- Store the created windows in an array
- Implement destroying of controls when mixer is changed / line selection is altered
- Implement generating layout for each new line
- Implement setting line name
- Resources have not yet been commited
- Sndvol32 is not yet functional
