Adds classes that allow building arbitrary query expressions and require
an instance to be provided to Geary.SearchQuery, to be set as a
property.
This enables query expressions to be parsed by clients instead of the
engine, in which ever whay they choose.
Stop needlessly wrapping object members and array elements in
variant variants.
Don't wrap object values in variants since the code is already using
vardicts for these. Return a variant array if a JS array contains values
of all the same type and don't wrap these in variants, else return
a tuple, which don't need to be wrapped either.
Engine mocks don't need to be in the `Geary` namespace, and including
them there makes it difficult to use them in client tests, so put them
all in their own name-space and corresponding directory.
Normalise to composed forms rather than decomposed forms, which would
replace diacritics on characters with combining chars, making them
disappear from the generated initials.
Fixes#735
The only reason it was in the engine was so it could be used by both
the client and the web extension, without worrying about the
webkit2gtk and webkit2gtk_web_extension packages conflicting. However
it didn't really belong there, and added a dependency for the engine
on javascriptcoregtk which doesn't belong. So this fixes all that.
Some software like the above will mangle From mailbox names by appending
"via Some Service" to the From mailbox name. This messes up generating
default avatars for the actual people sending these messages, so
attempt to de-mangle the names.
This involves moving primary originator determination from the engine
to the client, since it's now a policy thing. Add unit tests.
Don't try to dray null initials, actually return null per API contract
when no initials can be found, don't include non-alphanumerics in the
initials. Add test case.
