use add_flag_append more, correctly set a few flags

merge

added landing event handlers for cosmos.lua

rework compiler flags section a little, drop already enabled flags, add -Wextra

engine links

reverting 2 files I accidentally changed

this hid CFLAGS

reduce shove frequency (perf). reduce dX so that less time is spent sliding.

Reduce number of link errors

compile hwengine first, so that all other files are compiled too and don't call pas2c again

first commit, added cosmos(menu) map and lua script with some functionality

I should have specified locals

set one rule per file, only compiles a minimum number of files when one pascal file is modified

ok you need to escape rpath for pscal scripts after all... (reverts r571e55b32da5)

rtl always static

oops, fix setting linker flags for haskell executables

also these two files are dependency (they are not in the list because they are special pas2c files)

need to switch to frozen after deleteCI

set pascal files as dependency of the target writing the c files so that it will run again if you modify them

Configuration for tag display default

BOM, pas2c only support ASCII

poor AI thought he should avoid stepping on frozen crates, and jump for non-frozen ones

new FindClang.cmake

removed redundant band, added touch of consistency w/ everywhere else

fix a few loose ends here

First select group of templates, then pick template from selected group

add dummy typinfo header

Fix engine build when png lib isn't available

uscript rendering

Silly me
