Hidden tests now require positive filter match to be selected

Browse Source 
This also required some refactoring of how the pattern matching
works. This means that the concepts of include and exclude patterns
are no longer unified, with exclusion patterns working as just
negation of an inclusion patterns (which led to including hidden
tags by default, as they did not match the exclusion), but rather
both include and exclude patterns are handled separately.

The new logic is that given a filter and a test case, the test
case must match _all_ include patterns and _no_ exclude patterns
to be included by the filter. Furthermore, if the test case is
hidden, then the filter must have at least one include pattern
for the test case to be used.

Closes #1184

### Change semantics of `[.]` and tag exclusion
Currently, given these 2 tests
```cpp
TEST_CASE("A", "[.][foo]") {}
TEST_CASE("B", "[.][bar]") {}
```
specifying `[foo]` as the testspec will run test "A" and specifying
`~[foo]` will run test "B", even though it is hidden. Also, specifying
`~[baz]` will run both tests. This behaviour is often surprising and will
be changed so that hidden tests are included in a run only if they
positively match a testspec.
### Console Colour API
The API for Catch2's console colour will be changed to take an extra

* XmlReporter outputs a machine-parseable XML
* `TEST_CASE` description support has been removed
* If the second argument has text outside tags, the text will be ignored.
* Hidden test cases are no longer included just because they don't match an exclusion tag
* Previously, a `TEST_CASE("A", "[.foo]")` would be included by asking for `~[bar]`.
### Fixes
* The `INFO` macro no longer contains superfluous semicolon (#1456)
