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.

When an embedded process exits the main process receives a SIGCHLD. The
check on whether the embedded process is alive is done on input, so
forward an input of '\0' to get the embedded terminal to notice its
child is dead.
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.
UIEvent::StartupCheck was meant to notify the UI that a folder had made
progress and polling its async worker would return a
Result<Vec<Envelope>>. However the StartupCheck was received by
MailListing components which called account.status() which did the
polling. That means that if the polling got back results, the listing
would have to call account.status() again to show them. This is a
problem in configurations with only one account because there aren't any
other sources of event to force the listing to recheck account.status()
A new event UIEvent::WorkerProgress will do the job of notifying an
Account to poll its workers and the account will send a startupcheck if
it has made progress. That way the refresh progress is as follows:
Worker thread sends WorkerProgress event -> State calls appropriate
account's account.status() method -> account polls workers, and if there
are new results send StartupCheck events -> State passes StartupCheck
events to components -> Listings update themselves when they receive the
event
1. spawn thread to send ThreadPulses to the main event loop that "parks" until unparked from State
2. State unparks thread if there are accounts that are offline
3. thread sends ThreadPulse and parks again
4. State checks accounts again and so on.
