feat(mail): mail history query for the dashboard

Browse Source 
IMail::GetMailHistory and CountMailHistory return mail rows as stored,
deleted mail included, newest first, with the sender's and receiver's
accounts. Filters: character (sent or received), account, text in the
subject, body or a name (LIKE wildcards matched literally), state
(unread, read, attachment waiting, claimed, deleted) and whether to
include deleted mail. MySQL and SQLite share the SQL (MailSql.h).

Check: parity test ParitySeeded.Mail (GetMailHistory).
