Updated calendar dates for 2015.

• Added exercises to item-page-reference template.

Merge branch 'master' of https://github.com/Otago-InfoSci-Database/XML

• Fixed spacing of exercise labels.

• Added a horizontal-rule element. (I’m amazed we’ve never needed one before now!)

• Fixed vertical spacing of captions for floaters.

• Fixed bug that caused tables to be output twice in (X)HTML.

• Fixed broken document title suppression (doing it when it shouldn’t).

• Added suppress-latex-title attribute for (Xe)LaTeX.

• Added target attribute to hyperlinks for (X)HTML only.

• Corrected generation of value attributes for enumerated <li> elements in (X)HTML.

• Added latex-calendar-break template to support breaking a calendar across pages in (Xe)LaTeX. ...

• Refactored calendar tabular preamble and postamble into separate templates.
• Made use of tunnelled parameters to reduce the amount of explicit parameter passing.

• Changed expansion of semester codes to match University standard phrasing.

• Fixed bug where labs and tutorials hard-coded the default number of rows to 2 rather than @lectures-per-week.

• Removed unused variable.

• Corrected default number of rows to span for labs and tutorials (should be 2, not 1).

• Fixed bug that caused unnumbered lecture titles to be centred in (Xe)LaTeX.

• Fixed some errors in comments. ...

• Added support for multi-row lectures, laboratories and tutorials (closes #6).

• Added support for enabling/disabling lecture, laboratory and tutorial numbering, both globally and at the individual class level.

• Switched to using \def instead of \newcommand for pre-\begin{document} definitions, as it seems safer.

• Removed italic formatting from holiday week text in HTML mode for consistency.

• Fixed formatting of paragraphs with borders in LaTeX.

• Made the way fonts are deactivated more robust.

• Rolled back the italics for break weeks. Doesn’t look that great.

• Fixed silly copy-and-paste bug that caused closing brace in \fontspec group to not be emitted.

• Fixed typos in comments.

• Fixed conditional output of font selection code (previously the enclosed text would disappear if a font name wasn’t specified). ...

• Added apply-templates to HTML font selection.

• Added italics to LaTeX output for holiday weeks.

• Added font element to enable reasonably arbitrary typeface changes.

• Added support for teaching calendars that span multiple teaching periods: ...

– Added infosci:expand-period-code() function.
	– The global stylesheet variable $period-string is now set using infosci:expand-period-code().
	– Refactored output of calendar content (either as a LaTeX tabular or HTML table) into a callable template.
