Perl syntax highlighting: highlight interpolated variables and special characters in strings

[zenogantner]

It would be nice if interpolated variables and special characters would be highlighted with special colors, e.g.:

print "Hello\n" # 'Hello' and '\n' should have different colors.

print "val=$value" # 'val=' and '$value' should have different colors.

Scintilla does not do it yet: ​http://sourceforge.net/tracker/index.php?func=detail&aid=3076629&group_id=2439&atid=102439

Once upgraded to Scintilla 2.27 in Wx::Scintilla. I will begin fixing LexPerl?.cxx to include this feature.
