Many typo's

These were found using the command below searching for duplicated words,
and manually going through the results to remove the false positives and
reword the true positives. Sometimes I removed the doubled word and
sometimes I replaced the duplicated word.

The grep command:
grep -nIEr '\b([a-zA-Z]+)[[:space:]*]+\1\b' ./Ghidra
