- Added a ChunkMap class responsible for allocating new chunks to be downloaded, according to

- a given chunk strategy
	- the availablility map of each source 
- Integrated this into ftFileCreator
- added gui menu in file transfer+right click to change the chunk strategy: streaming vs. random

Next step: 
	- loading/saving file downloading state and availability map
	- displaying chunk details in the selected transfer tab (e.g. list of currently worked chunks, and their current downloading completion)
