Andrew Kesterson 63ce2b2a0b Implemented argument lists for functions (and commands). Implemented LEN and MID functions. Added functions to expression parsing before primaries so they can be included in calculations.

READY
10 A$ = "Hello, World!"
20 PRINT A$
30 B$ = MID(A$, 2, 6)
40 PRINT B$
50 C# = LEN(B$)
60 PRINT "String (" + A$ + ") has a length of " + LEN(A$) + " and substring (" + B$ +"
) has a length of " + C#
RUN
Hello, World!
llo,
String (Hello, World!) has a length of 13 and substring (llo,) has a length of 4
READY

basicparser_commands.go

Multiple statements per line (separated by : ) are working. Removed :ELSE from IF syntax until ELSE can be made its own command.
