Incorrect/misleading display of descriptions containing exponents

Exponents don't display properly in intellisense, hover, etc, so descriptions that have exponents in them display incorrect/misleading values.

Environment

• Operating System: Windows 7
• JDK version: 1.8.0_102
• Visual Studio Code version: 1.9.1
• Java extension version: 0.0.10

Steps To Reproduce

1. Type Integer.MIN_VALUE
2. Notice that both the autocompletion while typing and the tooltip from hovering over the name say that the minimum value of an int is -231 rather than the -2³¹ present in the Java documentation.

Integer.MAX_VALUE does the same thing on hover (231-1 rather than 2³¹-1) but also adds a slash in the autocompletion dialog (231\-1).
