g++ 5.4 detects the static bools as "unused", which is true - but also
intentional.
Removing the "static" adds a lot of unused symbols to the global pool,
but it also prevents any compiler from detecting the "not used" status.
* do not use std::abs() because math.h includes one, that converts ints
to double. Use own iabs(), which directly uses labs() instead.
* don't use the word "gamma" as name for variables
* don't use a homebrew round() function
An alias, that was at least once used with the new "tempalias" will not be
written to saved.cfg.
So, now there are four ways to create aliases:
1) alias (or "=")
General alias, who's value gets saved at game exit in saved.cfg, and
restored at the next restart - unless the alias was created at a time,
where persistidents was zero (usually during execution of the game's own
config files during startup).
2) const
Creates an alias, that can not be changed. Makes it harder for users
to destroy their config.
3) push
Reassigns an alias with a new value. After "pop", the old value is
restored. Allows the use of "local" aliases in scripts. Also avoids
name conflicts.
4) tempalias
Like "alias", but the value will not be written to saved.cfg.
The commit also changes aliases, written by the engine itself, to "temp":
gametimestart, __getmaprevisions

allows a SVAR to be assembled when needed
also:
* mapmsg is now a SVAR
* getmapmsg was removed (now: $mapmsg)
* new editsvar script to edit any SVAR in the console buffer
* nonfunctional menu removed
