Brief summary of issue / Description of requested feature:

Give the TTS queue a lot to work through. It stops at some point.

Steps to reproduce the issue / Reasons for adding feature:

Warning, repeating these steps may temporarily stop your TTS output. Could be resurrected mostly.

1. in any new/old profile, put the following commands in main window input:

lua ttsQueue("ok")
lua ttsQueue("this also")
lua ttsQueue("")
lua ttsQueue("")
lua ttsQueue("this not")
lua ttsGetQueue()

2. You will read an output like the following:

{
  "ok",
  "this also",
  "",
  "",
  "this not"
}

3. You would expect to hear: "ok. this also. this not".
4. You hear "ok. this also." Then you hear silence. A lot of silence. The silence never ends.
5. After a while, you put lua ttsGetQueue() again and see the following output:

{
  "",
  "this not"
}

6. At this point, you can try putting lua clearQueue() and/or lua ttsSpeak("ok") a few times to resurrect TTS

Error output / Expected result of feature

4. Queue should continue uninterrupted with the all lines of text regardless.
