Feature: Enhanced Proxies

[Wunder-Wulfe]

• Fixed blacklist to use frontier patterns instead of the previous pattern matching structure, which would erroneously detect statements like owner_velocity_forward() due to _for satisfying the previous [%s%p]for match. Now matches against %f[%a](for)%f[%A]

• Enables additional compilation mode, allowing use of local variables, if statements, and return statements

  • Provides alternative ways of computing proxies optimally, by re-using calculation results, or short circuit evaluations / early exits via if statements
  • Prohibits function declarations, loops, and modification of global variables for security/safety reasons. Modifying, assigning to, or creating globals will result in an error

• Improved readability / structure of expressions.lua code

  • Moved repetitive code into functions, and simplified logic
  • Additional logic moved into functions to make iteration and testing easier

Working Example

Proxy:

local r,g,b = 0,0,0

local walkspeed = sqrt(owner_velocity_forward()^2 + owner_velocity_right()^2)

r = (if_event "Grounded")

if walkspeed > 0.2 then
    g = 1
else
    g = 0
end

return r,g,b

Fixed commit to rebase correctly this time. Github desktop was breaking my repo.
