[Feature] Get java installpath automatically

[Griefed]

From a friendly user on Discord:

this line is wrong.
javaPath = "C:\\Program Files\\Java\\jdk1.8.0_271"

Because if i first run your jar on a Linux system, it needs to be able to say, "oh damn! I'm on Linux"
Of which you can then do
which java

and it will return a path to where the primary java is located, if you need a version, of that java you can get it from doing java -version or w/e the path was returned you know this last part I'm sure.
kreezxil@970AKRAIT:~/Software/ServerPackCreator$ which java /usr/bin/java
if you tackle the problem tho, you'll be more valuable to the crown tho.

Fixed as of version 1.0.1
