Boar should not be affected by FAT32 limits

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a repository on a FAT32 drive
2. Import a directory with a file with size > 4GB

What is the expected output? What do you see instead?

There is an error message. The operation should complete normally.

Due to how boar store files internally, file size limits imposed by the file 
system also affects boar. FAT32 is unfortunately still quite common as the 
default file system on portable media such as USB memory sticks and external 
HDDs. Boar should split large files so that a repository can always be stored 
on FAT32. FAT32 max file counts and filename limits are not expected to cause 
any problems.

There are possibly other file systems that should be supported by boar, but 
this issue covers only FAT32.
