File is overwritten if you don't use a -f flag

[jellelicht]

The invocation python C3P file.txt will erase the contents of file.txt
This is a easy typo to make, and it isn't even useful behaviour.

Thanks @wordempire!
I agree that it's a bug. I'll try to fix it soon.

perhaps you could include a -F Force flag that will make C3P overwrite any file without question.
Without -F C3P should always ask for confirmation before opening (and possibly overwriting) an existing file.

This would also mean that the unwashed masses can't have their files overwritten if they forget the -f flag;
Accidents can only happen if -F is included, which would of course be the sole responsibility of the user (rm -rf anyone?)

I've just changed the order of the flags in commit 5de7967. The input file is the positional argument at the end (the destination file is given with a -d flag). So this problem of accidental overwrite because of a missing flag will not be a problem anymore.
The reason for changing that order is mostly to do with my wish for this tool to be useful in a shebang (#!).
