tigefa4u projects Trac

1.0dev: Moved the `svn_fs` and `svn_prop` modules to `tracopt.versioncontrol.svn`.

Closes #10712.

1.0dev: add deprecation warning for suggest.js (closes #7355)

1.0dev: make ticket ranges wrap in batch events in the Timeline

Also wrap rendered TicketQuery in grouped compact format.

To make it possible to copy back ticket ranges links as now generated,
and still have them interpreted as the same range in the wiki, we
support ZWSP in the Ranges class.

This closes #10713.

ticket: add helper method `_cc_list`, hiding the use of Chrome

ticket: reformat imports in web_ui.py

1.0dev: Make it easy to revert individual ticket field changes, with a "revert" link next to each change in the preview. This also makes it simpler to resolve ticket edit conflicts.

Closes #7145.

1.0dev: in babel.js gettext, also format strings not found in catalog.

This is a follow-up to r11068, and actually the same kind of correction
that Jun had suggested for ngettext.

1.0dev: improve description of workflow sample plugins

1.0dev: Follow-ups to [11064], fixed failure of unit-tests for `[[Image]]` macro Python 2.7 cause U+200B is NOT space on 2.7. Added `trac.util.text.stripws`.

Closes #10668.

1.0dev: Give a better error message when the environment cannot be opened due to not finding `VERSION` or a wrong `VERSION` file.

Closes #10408.
