Change log shows nothing after update

[Eric23]

I assume there is meant to be text in this giant window that opened when I launched the game after updating it?

On linux, the directory where OpenRCT2 searches for changelog.txt is hardcoded to /usr/share/doc/openrct2. If you install OpenRCT2 in a different prefix (like /opt), changelog.txt can't be found.

Attached patch fixes this: it adds ${CMAKE_INSTALL_PREFIX}/${CMAKE_INSTALL_DOCDIR} to the search locations.

Hi Erik-Jan, could you create a pull request for that fix?
