Add Support for SourceBans++ 1.6.3 and higher

[Groruk]

Fixes #8

Context

SourceBans++ 1.6.3 introduced new native prefixes and a new library name (while still retaining its backward compatibility with SourceBans++ 1.6.2 and lower / SourceBans 1.4.11).

This PR fixes the native problems with SourceBans++ 1.6.3

Proposed Changes

• Include the new sourcebanspp.inc (Fully backwards compatible with SourceBans++ 1.6.2 and lower / SourceBans 1.4.11)

• Use the original SBBanPlayer instead of the short-lived SourceBans_BanPlayer (this also enables support for SourceBans 1.4.11)

• Integrate new SBPP_BanPlayer call for SourceBans++ 1.6.3

• Remove AskPluginLoad2 function (not needed [anymore])
