Instead of a single executable running different unit tests at the
same time, split the sqlobjects and import parts out of it.
While this currently duplicates the cmake boilerplate for each,
it allows to finetune each properly (like build only the sources for
it, in the future), and to call each separately.
Add the QTEST_MAIN in each test, and remove the manual QCoreApplication
handling in TestImport (handled by QTEST_MAIN).
The argument count (first parameter) is a reference, and thus must be
kept alive for the whole lifetime of the QCoreApplication instance,
as also the Qt apidocs say.
Also properly create a "string array" for the actual args, instead
of badly casting a string to that.
This fixes sporadic crashes in this test.
Use a common format for all include guards, make sure each header file
has one and make sure it's named after the file name.
And as a random extra in this commit: Make sure the gen_version.h file
generated by cmake ends with a line break.
Closes#59.
Add a new test class for testing the import functionality. Currently
it's only covers some test cases for the CSV import.
Since the function to test here (DBBrowserDB::decodeCSV) is part of the
DBBrowserDB class, that class has a reference to the main window and the
main window basically depends on the entire rest of the project the
makefile grew quite a bit unfortunately.
