This removes the special handling for it in the main loop.
Some functions and variables in the kill and secret managers were also given more meaningful names.
Fixes#313
* Remove fix16.h/cpp and utilise library from m_fixed.h.
* Extend m_fixed.h with two inline functions for int to/from float operations.
* Replace fix16_floor operations with those from xs_Float.h
* Replace multiple Q16.16 conversions from 0 to just be 0.
* Replaced all found in-game bit-shifts and multiplications/divisions with inline functions from m_fixed.h
* Replaced many casts of FRACUNIT as double in SW's panel.cpp as it is converted to double by way of type promotion.
* Fixed missed precision fixes in SW's panel.cpp where some types weren't declared correctly.
* Replaced 100+ `Cos()/Sin() >> 16` operations for Blood with inline functions `CosScale16()/SinScale16()`.
- Added names for sprite, wall and sector types
- Added gModernMap protection for using new features only on different version of map

These will have to do some texture management bookkeeping so directly changing the values is problematic.
This required changing the parameter interface in polymost.cpp because a few places hacked around with the global state to pass parameters to subfunctions.
- Added names for system RX/TX channels
- Detect if map requires new features to work properly via special TX and command
- Effect Gen update
