Fix issue with 'variable' being output as 'v*a*r*i*a*b*l*e'
reverting exponent to a carat, as that is used in most 'human readable' things
add ctrlseq so that textoutput correctly sees exponents and doesnt write '*^'
remove backslash in text output, as these are simply from latex commands and have no meaning for human-readable output
deal with situation of variable before command like sin/cos
fix *_ on text output
fix * being added after autocompleted functions like cos/sin
add option to change auto-unitalicize behavior, and create all-auto italicize for any function upon use of brackets.
