Improved blankposting (#256)

* Consolidate blankposting into singular log entries of "no message" instead of spamming the logs repeatedly when someone decides to keep switching emotes
Return proper blankpost checking to 2.8.5 (chatmessage_is_empty bool makes sure the chatbox doesn't appear - branch broke that behavior by never setting it)
More robust blankpost checking, meaning that passing a competely empty "" string will also count as a blankpost
Fix screenshake not working with blankposting by moving it before the chatmessage_is_empty check in start_chack_ticking() stage of the message parsing

* Allow user to send blankposts without even having to input a single spacebar, but only if last m_chatmessage CID matches ours.

* Reviews are cool and good👌
allow sending no-text chat message to server without weird cid checks (let the server validate if they want to do STR_OR_EMPTY or just STR) - doesn't break existing behavior and lets servers introduce the new one if they want to
Treat all blank/whitespace messages as blankposting and not just single-whitespace.
Remove chatmessage_is_empty bool because why the fuck would you even need it if you have m_chatmessage[MESSAGE] already
Simplify chatlogpiece log entry to not be a *temp pointer by suggestion

* another useless bool destroyed
Make "additive" have a very awesome emergent behavior with blankposting - keep showing the chatbox+message while only changing the emotes. Works with preanims too!
