Fixes #88.

Currently messages with long words (non-space separated) result in an expanded window size.

This commit changes the line wrapping mode to WORD_CHAR to allow for wrapping mid-word.

#81

Following the restructuring of the last commits.

Using a hack from Dino:
https://github.com/dino/dino/blob/v0.2.0/main/src/ui/chat_input/chat_text_view.vala#L51

"Entry" is a widget in GTK and "input" is something more generalized.

With an eventually upcoming file attachment button (and separate voice
button) the UI might become too clunky with a send button. In addition,
no other major desktop chatting program seems to have one, since sending
via pressing enter is the standard.

Basically reverts 6b9f691c

Crediting Dino.im for their work.

What's still needed is to only activate the scrollbar of the input when
it's needed. Otherwise the input gets too big.
