This adds over 1200 unit tests for parsing BBCode and Markdown. In the process of creating the unit tests, I also found and fixed a bunch of bugs.

Also Gets rid of the SMF\Time::$user_tz static property in order to avoid giving SMF\tests\Unit\TimeTest a bellyache.

I have been building tests for the parser, too. Mine are more focused and don't cover every single BBCode. I also noticed that there are several repeatable patterns that make that test file cumbersome to read. I'll need to condense those before adding my tests.

I also have some performance tweaks for the BBCode parser, but those will be put on the back burner to give way to the tests.

By all means add more tests. However, all of the existing ones, even when they seem repetitive, should stay as they are.

I wrote a script to programmatically generate tests using every possible combination of $input_types, $output_type, and $options for each input string. The naive version of that script generated over 14,000 tests, many of which were indeed repetitive in the sense that the different combinations of parameters made no difference to the output. So I added logic to winnow the pile down to only those tests where a change in the parameters made a difference to the result. If you examine the finalized list of tests in this PR, you'll see that each one has a distinct set of $input + $expected.

Here's the script I used to generate these tests. I just commented and uncommented the relevant strings to create the tests for basicBbcodeStringProvider(), basicMarkdownStringProvider(), and complexStringProvider().
