NPCServer updates

[Admins]

Today the npcservers have been updated. Here some of the updates:

- /style works again
- improved /scripthelp which also lists object types that match
- fixed int(random(lowerlimit, upperlimit)) which sometimes reached upperlimit (when the random number was too close to the upperlimit it was rounding to upperlimit)
- scripts can now access image files (png, gif, jpeg) and also files inside the levels folder if the npcserver has the rights for that
- if you call a function of another object which is non-public, then it will display that the function is not accessible, instead of saying that the function doesn't exist
- graal script now supports function objects: this will print "param: 123"

PHP Code:

function onCreated() {
  this.func = this.func1;
  this.func(123);
}
function func1(param) {
  echo("param: " @ param);
} 


You can also do this, but keep care to add a semicolon behind the function declaration:

PHP Code:

this.func = function() {
  echo("nameless function");
}; 


This is only working on serverside, it will work on clientside with the next Graal version.
There is a protection against unsetting functions, since often scripts use the same name for functions and variables. If the variable is not linking to a function but the script contains a function with that name, then it will use the function defined in the script instead. You can however link to another function.
