Text attributes have been rewritten as bit flags, so for example instead of
"BoldUnderline" you'd have to define "Bold | Underline" in your theme
settings.
Requested in #21
conf_override! wraps struct definitions and defines a secondary Override
struct that wraps each field in an Option. The macro mailbox_settings!
is used to select settings from an account & mailbox index. If a user defines an overriding setting, the macro returns the override instead of the immediately next in the hierarchy setting.
The selection is done for a specific field as follows:
if per-folder override is defined, return per-folder override
else if per-account override is defined, return per-account override
else return global setting field value.
Refactor Collection from melib to hold what folders have what envelopes.
Frontend accounts will now have a FolderEntry for each logical folder
and will unify many Account fields into one and eliminate a lot of
duplicate/dead code.
Use FolderHash directly as a cursor type for folders within an account
isntead of having a usize (being the order of the folder within the
account) and figuring out the folder_hash everytime it's needed.
Add OfflineListing for offline accounts and AccountStatusChange event.
Merge ui crate with root crate.
In preparation for uploading `meli` as a separate crate on crates.io.
Workspace crates will need to be published as well and having a separate
`ui` crate and binary perhaps doesn't make sense anymore.
