Add a new class for handling a process's environment variables.

First of all, make it a lot easier to access individual variables by
having them in an associative container (a QHash). This fixes task
232427, albeit one release later than I had originally planned.

On Windows, the variable names in the environment are
case-insensitive, so a direct QHash isn't a good solution. Implement
code that does the uppercasing on Windows and leaves untransformed on
other platforms.

Since we're doing this anyways, use QByteArray on Unix systems, since,
in theory, the environment could contain any random binary data, which
is not representable in QString.

Task-number: 232427
