Discovered that classes ( and possibly other splits could end up with an
empty/null member that still gets joined so I added a trim to the end of
all the joins in processStyleTags.
Added tests that SHOULD test for bloc-level and inline-span moustaches
with added attributes ( a=b )
Wraps with quotes ( a="b and c" )
Still does not work on Mustache Divs. UNsure where the failure is at the
moment. Even regressed "a:b and c" pattern on those.
This should match more economically and in line with marked
recomendations as well as not allow whitespace ( \s ) at the beginning
or end of a sub or superscript mark. Additionally, a failure in having
mixed sub and supers on the same line was corrected.
Uses ^^ for superscript and ^^^ subscript as wrappers in the same
pattern as italics and bold ( * and **, respectively)
Adds editor hot-keys and sytax highlighting. (CTRL-6/CTRL-7)
Exact values may not be ideal. Short of the suggestted overloading of ~,
I didn't see a better option for the delimiter.
This adds the ability to include attribute values for any element that
can be altered by a moustache.
Form:
```
{attribute=value}
example:
 {position:absolute,bottom:20px,left:130px,width:220px,a=b and c,g=h}
```
In order to permit spaces, the pattern matches for moustache code had to
remove the space character as a delimiter. I believe I have adequate
compensated.
This should solve #1488
