"Show type" popup suggestions

[develop7]

Repro:

• Select an expression and issue "Haskell → Show type" action (Alt=)
• A popup with type signature appears

Expected:

1. Monospace font (instead of proportional)
2. Wrapping (type signatures too wide to fit current screen should be wrapped)
3. Syntax highlighting (highlight arrows and parentheses with different colors)
4. Type signatures could be autoformatted, thus resolving point 2.

Thanks for reporting!

I have to investigate this.
