Font size standardisation for filenames, links, crumbs / Bug 6114:
- lonhtmlcommon::crumbs:
- Eliminated size (font resize) parameter: Always generate code which uses standard font size. Removed deprecated font size tag.
- Eliminated noformat parameter: The routine should generate content, not special styles or formats. If a different style/format is really needed, it can be added from outside. Due to consistency, currently no special styles/formats are used, only LC_filename. loncommon:CSTR_pageheader needs to be revisited anyway.
- Use LC_filename for path and filename
- Only single space before target attribute
- Standard code indention
- Decrease default font size for LC_filename
- No different font size for links (<a>)
- CSTR Header: only display lastitem when not empty
- Optimized line breaks on browse resource / import resource screen
