Update 1.2.49

• Update to ReIndev 2.8.1_6 from 2.8.1_5
• Remove hotfixes that were upstreamed into 2.8.1_6

Note: I upstream hotfixes and performance improvement from FoxLoader into ReIndev when possible.
This means if you use FoxLoader you get access to those bug fixes sooner and more often.

The following upstreamed hotfixes are:

• HiDPI issues with ReIndev (From 1.2.48)
• Wyvern crashing the game in some specific conditions. (From 1.2.46)
• Crash when quiting a world while editing a sign. (From 1.2.46)
• Misc network improvements by @kivattt (From 1.2.42)
