#278: fix blip code inconsistencies and clamp size value for backwards compatibility

[patrikjuvonen]

GitHub issue:
#278

Summary:

• Discovered by zHooP on Discord. Thanks.
• This bug has been in the client code forever.
• Code never checked if blip icon is valid.
• Code allowed any blip size.
• Made backwards compatible by clamping size value between 0 and 25 instead of returning false upon invalid size.
• If size is out of bounds client-side, it will output a debug warning about clamping that might affect behavior.

FYI: The AppVeyor build failed because it says the build took more than 60 minutes when the logs clearly shows it got stopped after ~12 minutes. Someone has to rerun the build.

has the size param changed from an unsigned char to int to satisfy Clamp?

That, but also to make sure if you passed a negative value as the argument, it would take that negative value and clamp it to 0 instead of some random value between the min and max depending on the integer overflow amount.
