Use the native TMX tile animation format

Rewrote the tile animation loading code based on XML tags, replacing
the code that loaded tile animations from tile properties.

Also made a number of code simplifications and optimizations:

* Replaced a number of pointer members with value members.
* Pass around Animation and TileAnimation by value, using std::move to
  avoid allocating copies.
* push -> emplace
* push_front -> emplace_front
* push_back -> emplace_back
* Use range-based for loops
* Use std::vector instead of std::list for storing affected tiles
  (less fragmentation)
* Avoid string copies and allocations while parsing CSV layer data.
* Replaced xmlNodeGetContent with directly accessing 'content'.
