Buggy HBL parser 2

[spond]

Expressions that use inline object definitions (e.g. matrices, dictionaries, substituted strings) are evaluated once and not updated if the inline object definitions change between calls.

For example

for (k = 0; k < 10; k+=1)
{
    str = ""+k;
    substitutedString = "`str`-substituted";
    fprintf (stdout, substitutedString, "\n");
}

Prints 0-substituted 10 times.

This issue has been resolved by introducing 'volatile' commands into the HBL parser. Basically, anything that has an inline variable definition that could change between calls (a matrix or a dictionary or a string with variable substitutions via backquotes) is now NOT compiled into an internal representation, but rather re-parsed from the command string in every call.
