Fixes#82.
The old behaviour was to parse the content of a widget or html element
in block mode if the opening tag was followed by a line break. The new
behaviour requires two line breaks.
This makes it possible to include linebreaks more liberally within
wikitext, although care must still be taken to only use double line
breaks when the block mode behaviour is desired.
The code change here is very simple, just a single line change in
html.js. Most of the other changes are to convert various single line
breaks into double line breaks.
In some timezones, (eg GMT+6) the modified timestamps for the
'TiddlerOne' and 'Tiddler Three' test tiddlers were actually on
the same day. This was causing the 'eachday' filter test to fail.
Similar to the fix in commit 8487221, this just adjusts the
timestamp to ensure the test passes in any timezone.
In certain timezones, 201304151312 UTC is not actually the same day
as 201304152219 any 201304151756. This was causing the test for the
'sameday' filter operator to fail. (I'm in GMT+10).
This is a quick-fix. I've just adjusted the timestamps to be close
together so they will be same day no matter what timezone you're in.
One consequence of wikifying macro attributes before use was that we
couldn’t have tiddler titles with wikitext syntax in, which was
definitely a problem.
Getting rid of the old widget mechanism files finally gives us a payoff
for all the refactoring. Still a bit of tidying up to do, and we need
to re-introduce the animation mechanisms.
The purpose is to allow attributes to be specified as macro
invocations. For example `<div myattr=<<mymacro param1 param3>>>`. The
parser needed sprucing up in order to copy with the nesting of angle
brackets. The refactoring has been done with an eye on using the same
technique in the filter expression parser (which is pretty messy at the
moment -- it throws exceptions for syntax errors, which is bad). Later
I'm hoping to extend the technique to create a more flexible table
parser.
