Item2370: TwistyPlugin generates illegal id= values when used in subwebs

If the TwistyPlugin is used in a subweb, it generates span tags with illegal ids.

For instance, if the subweb is called Main.Test, then the span ids for a twisty item in topic FooBar will be

<span id="twistyIdMain/TestFooBarlshow">
<span id="twistyIdMain/TestFoobarlhide">

Unfortunately, "/" is not a legal character in a id string.

This is fairly clearly fixable in _createId in TwistyPlugin.pm , possibly just by

$theWeb =~ s#/##o;

Is there likely to be any problem with the fact that the result could conceivably clash with another valid Web name?

---

The only time overlapping web/topic names would be a problem is with the remember="on" setting, that stores the twisty state in a cookie.

But it can be prevented by changing the / separator to for example subweb, for example twistyIdMainsubwebTestFoobarlshow.
