Bug fixes, see linked issues.

Minor enhancements

• added a function to clone computers in case of a technical problem in mid mission
• inverted scroll direction in terminal (now more intuitive)
• added a reset to the default armaOS texture if UI on texture was disabled mid mission to prevent misleading information on screen
• reduced network traffic by deleting/resetting some variables that are not needed on server
• neduced network traffic by cropping the terminal buffer to the last 100 lines when syncing back to server
