soywod/himalaya v1.0.0-beta.4 on GitHub

Added systemd service in assets/ folder.
Added configuration option message.delete.style that can be either folder (deleted messages are moved to the Trash folder, default style) or flag (deleted messages receive the Deleted flag).
Added --debug as an alias for RUST_LOG=debug.
Added --trace as an alias for RUST_LOG=trace and RUST_BACKTRACE=1.
Added notes about --debug and --trace when error occurs.

Added back the search feature: you can now give an optional filter and sort query at the end of the envelope list command. See envelope list --help or pimalaya.org for more detail on the search API.
Changed the envelope list folder argument due to the search query: it became a flag --folder|-f.
Made the global --config|-c option repeatable: the first option is considered the path to the main config, and successive options are considered partial overrides #184.
Refactored error management: error should be more clear, colored and can now contain spantrace and backtrace.
Made --help content wrapping properly thanks to the clap cargo feature wrap_help.
Improved template {new,reply,forward} command JSON output: they return now a JSON object with 3 properties:
- content: the content of the template
- cursor.row: the row at which the cursor should be placed by the interface using the template
- cursor.col: the column at which the cursor should be placed by the interface using the template

Fixed watch IMAP envelopes when folder was empty #179.
Prevented parsing of undefined config options #188.
Fixed In-Reply-To header being skipped from mailto URLs #194.
Fixed error page out of bounds when filtering envelopes returned an empty result #195.
