v0.2.2

This version fixes a critical bug which could cause the setup dialog to crash after linking to Dropbox. It also introduces support for file and folder names with multiple periods.

Added:

• Added support for file and folder names with two or more periods.
• Temporary autosave files that are created by macOS are now detected by their extension
  and excluded from syncing.
• More fine-grained errors, subclassed from MaestralApiError.
• Log all events of level INFO and higher to a rotating file in '~/.maestral/logs'. The
  log folder size will never exceed 6 MB.

Changed:

• Better handling when Dropbox resets a cursor: retry any files_list_folder calls and
  prompt the user to rebuild the index on files_list_folder_longpoll calls.
• Prepare for G-suite Dropbox integration: G-suite files such as Google docs and sheets
  will not be downloadable but can only be exported. Maestral will ignore such files.
• Moved deprecated API calls to v2.
• Better handling of OSErrors on download.
• Tweaks to logo.

Fixed:

• Fixed a bug which would prevent some error dialogs from being shown to the user.
• Fixed a bug which would cause the setup dialog to crash after linking to Dropbox.
