[v1.3] Now with less typos and bugs!

Another simple update to the dialogue lines and story according to the inputs I have received shortly after v1.2:

• Fixed missing symbols for certain dialogue lines caused by IDE
• Fixed missing context for certain dialogue lines
• Added clarification for certain ambiguous or unclear dialogue lines
• Changed the 'Preferences' menu name to 'Settings' as several users were confused about it
• Adjusted lines that were reported to be out-of-characters due to wrong choice of words
