GetScriptStringParam hook now enforces null-terminator

[MiranDMC]

Beside expected script name related tests failing now there is also problem with in print string test:

shortString a = 'From ACC' // 8 characters

as the a is assigned From AC

[x87]

as the a is assigned From AC

this is correct, as shortString variable is expected to contain a terminated string (7 chars max+nt)

[MiranDMC]

as the a is assigned From AC

this is correct, as shortString variable is expected to contain a terminated string (7 chars max+nt)

Let's not now combine source and destination terms together. Since the max len is defined by parameter type enforcing terminator is wasting one potential character.
