invalid tiddler IDs (due to spaces)

[FND]

As discussed here, tiddler IDs generated from the respective tiddler's title can contain spaces, resulting in invalid IDs. Thus spaces should be removed or replaced in IDs.

Rationale

Apart from conforming to web standards, this would also make it easier to use CSS ID selectors.

Potential Problems

Plugins assuming that the ID for a story tiddler is story.idPrefix + tiddler.title would become non-functional in some cases. However, fixing this should be very simple.

"Plugins assuming that the ID for a story tiddler is story.idPrefix + tiddler.title would become non-functional in some cases. However, fixing this should be very simple."

This assumption likely occurs in ALL plugins that are currently assembling tiddler DOM element IDs from tiddler titles, and would have a VERY LARGE IMPACT on the installed base, and should NOT be done without extensive review and a lengthy 'beta' shakedown.

If at all possible, a backward-compatible switch should be provided to ease the upgrade path (allowing older plugins to continue working until users choose to update them).

While the rationale given for this change makes sense (i.e., web standards, and CSS use of ID selectors), given the potential problems that can arise, I don't think it is a compelling justification for making this change.
