Release v0.7.0

[soywod]

Added

• Added offline support with the account sync command to synchronize
  a backend to a local Maildir backend [#342].
• Added the flag --disable-cache to not use the local Maildir
  backend.
• Added the email composer (from its own
  repository) [#341].
• Added Musl builds to releases [#356].
• Added himalaya man command to generate man page [Add man page #419].

Changed

• Made commands read, attachments, flags, copy, move,
  delete accept multiple ids.
• Flipped arguments ids and folder for commands copy and move
  in order the folder not to be considered as an id.

Fixed

• Fixed missing folder aliases [#430].

Removed

• Removed the -a|--attachment argument from write, reply and
  forward commands. Instead you can attach documents directly from
  the template using the syntax <#part filename=/path/to/you/document.ext>.
• Removed the -e|--encrypt flag from write, reply and forward
  commands. Instead you can encrypt and sign parts directly from the
  template using the syntax <#part type=text/plain encrypt=command sign=command>Hello!<#/part>.
• Removed the -l|--log-level option, use instead the RUST_LOG
  environment variable (see the
  wiki)

himalaya-lib v0.5.0

Added

• Made backend functions accept a vector of id instead of a single id
  [#20].
• Added function Backend::purge_folder that removes all emails
  inside a folder.
• Added new Backend functions using the internal id:
  • get_envelope_internal: gets an envelope by its internal id
  • add_email_internal: adds an email and returns its internal id
  • get_emails_internal: gets emails by their internal id
  • copy_emails_internal: copies emails by their internal id
  • move_emails_internal: copies emails by their internal id
  • delete_emails_internal: copies emails by their internal id
  • add_flags_internal: adds emails flags by their internal id
  • set_flags_internal: set emails flags by their internal id
  • remove_flags_internal: removes emails flags by their internal id
• Added emails synchronization feature. Backends that implement the
  ThreadSafeBackend trait inherit the sync function that
  synchronizes all folders and emails with a local Maildir instance.
• Added Backend::sync function and link ThreadSafeBackend::sync to
  it for the IMAP and the Maildir backends.
• Added the ability to URL encode Maildir folders (in order to fix
  path collisions, for eg [Gmail]/Sent). Also added a
  MaildirBackendBuilder to facilitate the usage of the
  url_encoded_folders option.
• Added a process lock for ThreadSafeBackend::sync, this way only
  one synchronization can be performed at a time (for a same account).

Fixed

• Used native IMAP commands copy and mv.
• Fixed maildir date envelope parsing.
• Fixed inline attachments not collected.

Changed

• Improved Backend method names. Also replaced the self mut by a
  RefCell.
• Simplified the Email struct: there is no custom implementation
  with custom fields. Now, the Email struct is just a wrapper around
  mailparse::ParsedMail.
• Improved Flag structures.
• Changed Backend trait functions due to [#20]:
  • list_envelope => list_envelopes
  • search_envelope => search_envelopes
  • get_email => get_emails, takes now ids: Vec<&str> and
    returns an Emails structure instead of an Email)
  • copy_email => copy_emails, takes now ids: Vec<&str>.
  • move_email => move_emails, takes now ids: Vec<&str>.
  • delete_email => delete_emails, takes now ids: Vec<&str>.
  • add_flags takes now ids: Vec<&str> and flags: &Flags.
  • set_flags takes now ids: Vec<&str> and flags: &Flags.
  • remove_flags takes now ids: Vec<&str> and flags: &Flags.

Removed

• The email::Tpl structure moved to its own
  repository.
• Encryption and signed moved with the email::Tpl in its own
  repository.
