Highlight matching parentheses

There are three supported style of paren matching, based loosely on the Emacs options. The style is select based on the HILITE_STYLE attribute; it can be changed used the set_style method.

The supported styles are:

default

When a right paren is typed, highlight the matching left paren for 1/2 sec.

expression

When a right paren is typed, highlight the entire expression from the left paren to the right paren.

TODO: - fix interaction with CallTips - extend IDLE with configuration dialog to change options - implement rest of Emacs highlight styles (see below) - print mismatch warning in IDLE status window

Note: In Emacs, there are several styles of highlight where the matching paren is highlighted whenever the cursor is immediately to the right of a right paren. I don't know how to do that in Tk, so I haven't bothered.
