Renamed new->newobj since new is a C++ keyword
Constify some char* string inputs, and modify behaviors of functions (in)directly called by US_Print and US_CPrint. Originally the latter two temporarily replaced each line newline char with a NUL terminator, leading to undefined behaviors (reproduced crashes). Should be better than an earlier workaround using a copy in a (two small) static buffer.
ClipToEnds: Comparisons of y should be unsigned (fixes King Boobus Tuber explosion)
Fixed some compilation warnings
Missed this minor C string literals related change in id_vw_ac.c
Converted newlines to LF in id_vw_a.c and id_vw_ac.c, removed Turbo C project file
Added compatibility with Keen Dreams, registered v1.93 (technically v1.92 plus minor diff from Blzut3), and shareware v1.20. These versions look almost identical to shareware v1.13.
