does not always read all byte

[gawric]

Hello
RAROScope does not always read all bytes from inputstream.availabes (java does not recommend to use)
need to fix a piece of code->
in RARFiles

public RARFile(InputStream stream) throws IOException {
this.stream = stream;

    this.available = this.stream.availabel

on

public RARFile(FileInputStream stream<--) throws IOException {
this.stream = stream;

    this.available = this.stream.getChannel().size()<---;

for Cyrillic readability
entry.setName(new String(name ));
on
entry.setName(new String(name , "CP866"));
