Login Purification + Optimized currenttime calls + Standardized WZ

Repelled ultimately the game-breaking issue that was introduced recently on the revamp of the login phase.
Optimized the getcurrenttime calls to the OS. Made most of the handler calls fetch directly from the Server object instead, the Server itself delegated with periodically updating the current time value. The result is an slightly delayed currenttime, backed with realtime value update within minutes.
Protected concurrently inventory sort handlers. Expected no more NullPointers from the sorting feature.
Added a server flag to limit cash items being sold on player shops/hired merchants.
Stabilized the MapleTV mechanics, and activities properly split by world.
Normalized Character.wz: equipments supposed to have the "cash" property now implements it.
Normalized String.wz: every item that doesn't have a "name" property now implements it.
Normalized the XMLs that lost indentation on the last source update.
New tool: MapleInvalidItemWithNoNameFetcher. Fetches and reports itemids throughout the XMLs that doesn't contain the "name" property and equipments that lacks "cash" property.

Frolic Omniknight references aside, if you have run into any more issues regarding the new login system, please open an issue and show the steps you've done to reach the problem.

-========================
-BUILD OUTPUT DESCRIPTION
-========================
-
-When you build an Java application project that has a main class, the IDE
-automatically copies all of the JAR
-files on the projects classpath to your projects dist/lib folder. The IDE
-also adds each of the JAR files to the Class-Path element in the application
-JAR files manifest file (MANIFEST.MF).
-
-To run the project from the command line, go to the dist folder and
-type the following:
-
-java -jar "MapleIdRetriever.jar" 
-
-To distribute this project, zip up the dist folder (including the lib folder)
-and distribute the ZIP file.
-
-Notes:
-
-* If two JAR files on the project classpath have the same name, only the first
-JAR file is copied to the lib folder.
-* Only JAR files are copied to the lib folder.
-If the classpath contains other types of files or folders, these files (folders)
-are not copied.
-* If a library on the projects classpath also has a Class-Path element
-specified in the manifest,the content of the Class-Path element has to be on
-the projects runtime path.
-* To set a main class in a standard Java project, right-click the project node
-in the Projects window and choose Properties. Then click Run and enter the
-class name in the Main Class field. Alternatively, you can manually type the
-class name in the manifest Main-Class element.
