Support <, >, |, and long-form symbols. Fix #662

Add long-form aliases for various text symbols

* \textgreater is an alias for > in text mode
* \textless is an alias for < in text mode
* \textbar is an alias for | in text mode
* \textdollar is an alias for \$ in text mode
* \textunderscore is an alias for \_ in text mode
* \textbraceleft is an alias for \{ in text mode
* \textbraceright is an alias for \} in text mode
* \textless is an alias for < in text mode
* \textgreater is an alias for > in text mode
* \textbar is an alias for | in text mode
* \textbardbl is an alias for \| in text mode
* \textendash is an alias for -- in text mode
* \textemdash is an alias for --- in text mode
* \textquoteleft is an alias for ` in text mode
* \textquoteright is an alias for ' in text mode
* \textquotedblleft is an alias for `` in text mode
* \textquotedblright is an alias for '' in text mode
* \textdagger is an alias for \dag in text mode
* \textdaggerdbl is an alias for \ddag in text mode
* \textsterling is an alias for \pounds in text mode
* \dag, \ddag work in text mode
* \circledR, \checkmark, \pounds work in text mode too
* Extend Symbols1 test to test \pounds and \textdollar in \text
* Add note about \pounds in text vs. math mode
