38f6e8c4f1 Formula engine: Add string escapes mechanism 
This builds on the string substitution syntax:
- [(] means an open bracket
- [)] means a close bracket
- ['] means a single quote / apostrophe

The tokenizer is now aware of string substitutions, making this possible
as well as the nesting of strings within string substitutions.

240b5f61a7 Output formula errors in unit filters to WML error stream

26a2638f2c Make the formula and Lua views of a unit coincide more closely 
Several keys were either missing or misnamed in the formula view.
These have been changed to match the Lua and WML names for the keys.
This affects canrecruit, moves, and max_moves, as well as status.

In addition, a large number of keys were missing entirely from the formula view.
Most of these keys have now been added and can be accessed from formulas.
A few that have little use in filters (such as image_mods or profile) are still missing.

The Lua view missed a few keys that the formula view did provide.
Although these could in principle have been obtained by using the special __cfg key,
they have now been added to the Lua view anyway.
