Perform Temporary Caching

[TheNexusAvenger]

Closes #117
Re-do of #174
Includes #175

This pull request is a redo of the improving world load time enhancement, which had a very high memory usage. This version is able to get to <15 seconds from world startup to the player loading like the last pull request, but results in the world loading in at <160 MBs instead of ~280 MBs. This is done by briefly caching tables for a couple of seconds when read so that a sudden amount of reads doesn't constantly re-read the database while also not causing the memory hit of keeping all the tables in memory as structs.

Last time, it was found that using caching for some components would result in load times in the minutes. However, I found that there is an inefficiency with some of the table reads regarding Lot.GetComponentId. There were some cases that would call it in a Linq statement, like the DestroyableComponent, which causes a database table read with each cycle instead of once before the Linq statement, like the new code. Table caching with the new method brought my Avant Gardens load time from >50 seconds to <30, and this change brought it from <30 to <15.

Just a few minor style changes. Overall an amazing change that I've been looking forward to for a long time. Memory usage is completely within margin now too imo.
