Load std.cfg before all other libraries ( #1740 )
...
- CLI: Save the libraries that should be loaded to a list and load them
after the std.cfg has been loaded.
- GUI: Load std.cfg (and windows.cfg / posix.cfg when applicable) before
setting other options and loading the other libraries.
In the project-file-dialog the std.cfg is searched first. If some
other library fails to load is is retried with first loading std.cfg.
- boost.cfg: Enable containers that depend on std containers.

Handle concatenated string and char literals
...
This handles concatenated strings and characters from simplecpp.
Previously, L'c' would be preprocessed to the tokens "L" and "'c'".
cppcheck would then remove the "L" token and set "'c'" to be a wide
character literal. Now, it needs to remove the prefix instead.
When doing this, add handling of utf32 encoded literals (U) and UTF-8
encoded literals (u8).
