Feature request: var strings

[hmedina]

%var: "foo" Gives an "illegal definition error". It would be useful if one could define variables that hold strings, allowing for example the modification of a snapshot file name vía the command line.

%var: 'foo' "bar"
%mod: [true] do $SNAPSHOT 'foo'.ka

Using $KaSim -var foo baz to produce a snapshot named baz.ka
