Added support of cyrillic characters output on companion devices with SSD1306 display. Use -D OLED_RU=1 with -D DISPLAY_CLASS=SSD1306Display for enable. Fixed bug with "glueing" next message preview with current message preview for messages ended with trimmed UTF-8 sequence. Fixed bug with incorrect trimming of UTF-8 message previews.
