We now have taskbar icon flash and a Lua addon

Targeting following vision and raid mark

• Added functions to target raid marks.
• World boss targeting now obey line of sight either.

Now we have nearly perfect Classic nameplates

UnitXP_SP3.dll:

• I solved some technical problem, now nameplate's distance/hiding is NEARLY PERFECT like Classic.
• The getTickCount function is deleted, because I no longer need it for nameplate refresh and game provide its own timer function with same capability. Now nameplates need no refresh at all. No flash, no complex switches anymore.
• nextEnemyConsideringDistance and previousEnemyConsideringDistance functions now have a little bit further melee range, increased from 5 yards to 8 yards.

sideload-DLL.dll:

• Now loader would attempt Load procedure in libraries regardless of file names.

Rework targeting and add Notify function

UnitXP_SP3.dll:

1. Targeting functions are reworked. They need more test. If you have issue or suggestion, please be kind to tell me.

TAB key now works

UnitXP_SP3.dll:

• Add new targeting function to replace default TAB

sideload-DLL.dll:

• Loader would self-eject itself from game when job is done
• Loader would read dlls.txt to load mods. It should work the same way as VanillaFixes loader. Thanks to hannesmann.
