Convert to utf-8.

Updated the `trac.config.Configuration.get*() and Section.get*()` methods to be more consistent in their input and return values - with recommended default of string or 'base type' signified by method name, and always looking to return the 'base type'.

Introduces a `Configuration.has_option(section, option)` that checks for the existence of an option somewhere in project trac.ini file, inherited trac.ini file, or in the options registry.

Updated method documentation + added some tests.

Closing #4977.

Fix matching for redirect after login from another project, for a special case where one project name (referrer) was a substring of the other (project for login).

Closes #3048.

Fixing a display bug when user doesn't have `SEARCH_VIEW` permissions.

Restoring 0.10 behaviour of form always being part of the page, but hiding the fields if not permitted to view. Fixes #5400.

Fix fine grained permission check for attachment change entries in ticket change history.

Follow-up to r6249: when previewing a ticket, we need to reset the URL to /ticket/xxx, discarding the eventual anchor that might already be present in the URL. Otherwise, we'll be targeted to that anchor and we'll probably miss the top of the page containing the preview and the eventual warnings.

Follow-up to r4573: the border-collapse mode for the table.code is useful also in other contexts, like for attachments.

When expanding a directory in the TracBrowser, the name column could sometimes be badly wrapped.

The fix is not perfect, as instead of wrapping, there could be a small overlap of the name on the size column. That's far less serious than the original issue though, as that column is empty for directories and the problem only occurs for directories, AFAICT.

Fixes #5277.

Fix uninitialized variable bug in `RepositoryManager.get_resource_description`.

Add a first version for Thai translations.
