Review request for KDevelop and Morten Volden.


Description
-------

Fix classification of error lines which look as
"file.cpp:100:10: error: 'SomeSymbolWithWarningInItsName' was not declared in this scope".

Here, we have an error pattern but also a "warning" keyword which actually is a part of symbol name. But existing code thinks that any appearance of "warning"/"info"/"note" in text is more important than the error pattern.

Fix this by
1) checking for all patterns in a uniform manner (loop for "string<->classification" pairs, not just for strings), and
2) picking the pattern which happened most early (to the left) in string.

Testing
-------

- Built kdevplatform+kdevelop with a couple of these lines, ensured they highlight as expected;
- Improved existing unit-tests to catch the error in question.


Thanks,

Ivan Shapovalov
