Fix data tooltip panic (#123)

* Fix data tooltip panic

Prevents panicing when attempting to display the data tooltip for a symbol that is too large by just using as many bytes as needed from the begging of the symbol.

* Don't attempt to interpret wrongly sized data

* Reference data display improvment issue

* Log failure to display a symbol's value
