Correction of BUG in subroutine parser and Support for multiple terminals

[marcsosduma]

Support for multiple terminals – allows the Linux system to use not only XTerm but also gnome-terminal, konsole (KDE), and xfce4-terminal.

Bug in parser – in some cases, the snippet "// fix new codegen - new" was causing the parser to change the line number of the corresponding C code line after the "/* Program exit */" tag.
