[PATCH 09/18] text: add support for invoke_action request

[Jan Arne Petersen]

From: Jan Arne Petersen <jpetersen at openismus.com>

Add a request to be called by the client when the word currently being
composed is tapped by the user. Input methods often use this information
to offer more word suggestions to the user.
