Server-side improvements

Worked on stability - should solve those problems which crashed server under peak load. Now it should just slow down :D Thanks everyone who became part of that pleasant problem, welcome aboard :)

Portable version

Added new button to main web page which allow to download archive with the most recent version. It will be fully portable with a config that is separate from the main app. This mechanism has already been tested for a few months in Packs, so should work without major issues.

p.s. Please note that portable version is not available for Stable yet, it will be available right after I will push alpha to stable in the next few days.

Bugfixes/Improvements

• [Scripting] Added TargetWindow to ISendInputUnstableScriptingApi - this allows to use Windows Message API and send inputs to background windows.
• [UI] Improved Import/Export dialogs error handling - errors should be more meaningful now and shown in a more presentable way
• [UI] Added badge which shows how many auras are there in Archived state. This is god-forbidden functionality which allows to Archive(aka unload and hide) auras which you currently do not use - this speeds up app load process quite a lot.
