hlein b595cc0fb5 Various cleanups (#363) 
* Typo fix.

* Style change: always use $(), never ``.

The Lynis code already mostly used $(), but backticks were sprinkled
around.  Converted all of them.

* Lots of minor spelling/typo fixes.

FWIW these were found with:

  find . -type f -print0 | xargs -0 cat | aspell list | sort -u | egrep '^[a-z]+$' | less

And then reviewing the list to pick out things that looked like
misspelled words as opposed to variables, etc., and then manual
inspection of context to determine the intention.
