Sanitize load_amxscript() and add load_amxscript_ex/MF_LoadAmxScriptEx() requiring error max length (#530)
* Add a saner version of load_amxscript and use SafeStrcpy/Sprintf

* Reflect the change in core

* Add LoadAmxScriptEx API function

* Reflect the change in CSX

* Reflect the change in DodX

* Reflect the change in TFCX

* Reflect the change in TSX

* Add few comments
