Commit 9c72ebccd3 introduced a bug: all template strings are validated against the disc template RegEx (which, for example, is wrong if we're testing the track template).
`os.pathconf()` expects a bytes object, but the path is stored as a
unicode object. Since there's no specified encoding, Python chokes when
trying to convert it to a bytes object. Explicitly encoding it as UTF-8
allows Python to change it to a bytes object smoothly.

* Limit length of filenames
If whipper generated filenames are longer thant the maximum value supported by the filesystem, the I/O operations are going to fail.
With this commit filenames which may be too long are truncated to the maximum allowable length.
Fixes#197.
This commit also includes:
- whitespace / code formatting fixes
- slight syntax related changes: except <exception_name>, e -> except <exception_name> as e
- 3 pointless instructions instances have been rewritten [sorted] (spotted by semi-automatic check)
The unrelated changes shouldn't have any real impact on whipper's behaviour.
