Add textdraw font boundary

[mysy00]

Describe the bug
Server doesn't check if given font in TextDrawFont (I assume it's the same for per player textdraws) is a valid font and providing one that's greater than 16 crashes the SA:MP client.

To Reproduce
Create a textdraw and set its font to a value that's greater than 16.
I used this one for a quick test: https://tutplusplus.blogspot.com/2010/11/samp-scripting-tutorial-create-textdraw.html

Expected behavior
Check the boundaries and in case they are invalid, show a message in the console and don't apply any action.
The function should also return false to indicate it failed.

Screenshots and/or logs
If applicable, add screenshots and/or log output to help explain your problem.

Release version

Fixed in #737
The behavior now is if you use a textdraw font higher than or equal to 16, or lower than 0, it falls back to textdraw font 0, and still returns true
