Fixed new drying racks being invisible

- Switched around endothermic fire and furnace due to flingomatic range issues

- Added fireflies to the preset

- Updated stone fruit bushes in the new preset to all be the same stage of ripeness

Added a new preset -- Ocean Tree Base!

- Fixed null reference exception that could occur in rare cases

- Data can now be written again; written files can now be found in the unsafedata directory (it's not actually unsafe, Klei just puts all written files there now)
- Fixed invisible Great Tree Trunks

- Fixed a crash relating to interrupting auto-work actions

- Optimized the second half of the code, if anybody decides to pick up this project after me it will actually be readable now. (If there's any bugs or crashes let me know)

Significant code optimization on several files (more to come soon). My tests appear good but let me know if i missed any bugs.

Also updated the Chinese translation and added a Korean translation.
