Add minor fixes

• Add property names to dummy friend declaration in common/property.hh to address #124 (closed)
• Add convenience overloads for UsedProgram::compute accepting glm::uvec2 and glm::uvec3
• Enforce left pointer alignment in clang-format (int* ptr instead of int *ptr)
• Apply clang-format to all files (Causes a lot of diff, maybe just let this happen on its own over time instead)
