Itch-dl

- Make most CLI arguments configurable from the settings file, and vice versa (fixes 24). Exceptions:
- Downloaded URLs and the selected profile name is still CLI-only.
- Using `--verbose` will debug print the selected config path before settings are read from disk.
- The [Configuration Files](https://github.com/DragoonAethis/itch-dl/wiki/Configuration-Files) wiki page was updated with all the new options.

- Added the ability to filter downloaded files by a regexp or a shell-style glob (fixes 23):
- `--filter-files-glob` lets you filter filenames with a shell-style glob ([fnmatch](https://docs.python.org/3/library/fnmatch.html) to be specific)
- `--filter-files-regex` filters with a [Python regex](https://docs.python.org/3/library/re.html)
- In both cases, the provided pattern must match the full file name to download that. Skipped files are logged.

- Added support for creator and community profile pages (fixes 22).

- Fixed a download failure in case where the Itch API returns the expected decompressed file size, but serves compressed archives from its download endpoint (fixes 21)
- Note: 0.4.2 was skipped as I accidentally left in a verbose debug print while implementing that fix, but noticed it after pushing the release to PyPI. Oops, one more version it is.

- Fixed a crash while attempting to download access restricted title pages. They are currently not supported, but this allows downloading libraries or bundles with restricted items without crashing.

- Fixed crashes with `--mirror-web` being unable to parse the new timestamp format - thanks mlewisa for the bugfix!
- Added support for downloading My Purchases and Collections - thanks to triple-j for this change!
- Misc dependency and docs updates.

Apologies for updates being this slow, looks like I'm not handling this project very well...
