Use LRU cache for ESMReaders. When cache capacity is reached close least
recently used ESMReader. Remember the file name if a reader was open. Once the
reader requested again open the file if there is stored name for it. Put
released ESMReader to the back of the free items list. Close ESMReader's from
the front of the free items list.
Cached item can be used only by one client at the same time. If the same item is
requested twice exception is thrown. This should never happen in practice. If
this happens need to fix the client logic.
It's allowed to go over the capacity limit when requesting different readers.
Ideally this should never happen but there will be system error anyway
signalizing about too many open files. Need to fix client logic in this case.
All places that were using a vector of ESMReaders now using the cache. Cache is
local for each use case and there is no need for a thread safety.

The progress is not particularly accurate. It simply uses the current / total number of records written/read as indication. Cell records are currently the largest by far, but there is a good chance that could be optimized using a change tracking system.

- Re-implement some patches that were broken by the removal of reclists.hpp and store.cpp/.hpp.
- NOTE: Not everything works as before, I'll have to test some more stuff before we are back to where we were.
