Search for users to start a new DM.
Hooks up the create room UI to the matrix client to get
search results. Searches are debounced for 500ms and
only executed when 3 or more characters are entered.
Wrap the result state so we can distinguish between
"no results because we haven't searched yet" and
"no results because the API returned nothing", and
add a "No results found" message in the UI for the
latter case.
Closes#95
Adds a CTA on the room list to view invites if there are any.
The invite list presents each invite with accept/decline buttons
and (for room invites) the sender details.
Fixes#102
The rustsdk library wasn't included in the gradle build because
it still used a groovy build file (and settings.gradle includes
projects based on `build.gradle.kts` existing).
Also reword the onboarding docs slightly to clarify the deps
that need changing
