Windows does not allow for a colon in the file name, and this will cause the sync to hault

[bryancasler]

Windows will not allow for a colon in a path or file name, among others. If that happens the sync errors out and grinds to a stop. Was unsure if this belonged in the putio-sync or putio-sync-desktop repo so I've posted it in both.

Two changes could be made to address this:

1) Remove colons.

2) When this error is encountered, log it, and continue to the next file

This is the full list of restricted characters that can not be in a path or file URL on Windows. In practice, all of them should be removed.

• < (less than)
• > (greater than)
• : (colon)
• " (double quote)
• / (forward slash)
• \ (backslash)
• | (vertical bar or pipe)
• ? (question mark)
• * (asterisk)

For now I chose to skip syncing the files containing restricted characters because it was simple and easy. If there will be demand for it we can think of a more complex solution.
