Release 0.2.1

• added a new function samp.callNativeFloat
  works exactly like samp.callNative but return value will be a float, only works when reference specifiers aren't provided in format parameter
• changed predefined event names and made them better following the scheme that were used
• a few new events added, supporting 0.3DL callbacks now
• (internal) changes in Config class for taking advantage of YAML and JSON parsers both together without writing the same code twice

PS: also now there's a TypeScript definitions package for samp-node thanks to @pkfln
