Client: Fix skill unpacking during bootstrap

[dannote]

Hi there!

I've been trying to launch the compiled runescape-client with my own applet loader and got this exception:

	at BZip2Decompressor.BZip2Decompressor_decompress(BZip2Decompressor.java:197)
	at BZip2Decompressor.BZip2Decompressor_decompress(BZip2Decompressor.java:33)
	at Skills.decompressBytes(Skills.java:51)
	at AbstractArchive.decodeIndex(AbstractArchive.java:100)
	at Archive.write(Archive.java:184)
	at Client.doCycleJs5(Client.java:2611)

	at GameShell.clientTick(GameShell.java:588)
	at GameShell.run(GameShell.java:916)
	at java.base/java.lang.Thread.run(Thread.java:830)

I compared the code with a previously decompiled version and discovered that this constant should be set to 1. Now everything works fine.

While I don't have any problem merging this, it's fixing a symptom, and not the problem itself, which lays somewhere in the arithmetic part of deobfuscator.

There's also going to be more problems further along the line of running runescape-client, keep that in mind.
