Whipper's caching implementation causes a few issues (#196, #230, [#321 (comment)](https://github.com/whipper-team/whipper/pull/321#issuecomment-437588821)) and complicates the code: it's better to drop this feature.
The rip resume feature doesn't work anymore: if possible it will be restored in the future.
* Remove caching item from TODO
* Delete unneeded files related to caching
* Update 'common/directory.py' & 'test/test_common_directory.py' (caching removal)
* Update 'common/accurip.py' & 'test/test_common_accurip.py' (caching removal)
* Update 'common/program.py' (caching removal)
* Update 'command/cd.py' (caching removal)
This fixes#335, fixes#196 and fixes#230.

```
The test fails because if either nextTrack.session or thisTrack.session are None the if is false and the instructions inside it aren't executed. The check for None is needed because Python 3 doesn't allow NoneType comparisons (in Python 2 that was possible).
IIRC correctly in that test nextTrack.session has value 2 while thisTrack.session is None. That means the Python 2 version evaluates the if condition to true, while the Python 3 version in the first commit does not.
With this change both of the values of nextTrack.session and thisTrack.session are compared as int (if None, the value 1 is used for the comparison - as in disc session 1).
Regression introduced in 64dd9d843a.

* Update failing AccurateRipResponse tests [1/2]
The failures seem to be caused by a remote metadata change (metadata from AccurateRip about a release ID changed) which means some of the asserts related to a specific release ID are failing. I've fixed this issue with two commits.
This is part 1: here I've updated the confidence values of two tracks making it agree with AccurateRip's remote.
* Update failing AccurateRipResponse tests [2/2]
This is part 2: here I've replaced the outdated AccurateRip bin file with a freshly downloaded one.
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.
- output path no longer has fallbacks
- refactor accuraterip cache
- use requests to download accuraterip entries
- add tests for accuraterip functionality
- remove gobject support from accuraterip-checksum calculation
- default track template now includes extension
- begin to remove support for continuing rip
- begin to use print instead of sys.stdout.write() throughout
