FixInsight warnings

Hi Jens,

I ran FixInsight over the System.Console unit and it reported a number of warnings. Would you accept a PR that fixes these?
I didn't take a look if they can all be fixed easily.

Here's the complete list:

[FixInsight Convention] System.Console.pas(932): C101 Method 'Console.MoveBufferArea' is too long (62 lines)
[FixInsight Convention] System.Console.pas(923): C102 Too many parameters in 'Console.MoveBufferArea' (9 parameters)
[FixInsight Convention] System.Console.pas(923): C103 Too many variables in 'Console.MoveBufferArea' (10 variables)
[FixInsight Convention] System.Console.pas(346): C104 Class name 'Console' should start with 'T'
[FixInsight Convention] System.Console.pas(348): C107 Class field name 'DefaultTextAttributes' should start with 'F'
[FixInsight Convention] System.Console.pas(351): C107 Class field name 'StdErr' should start with 'F'
[FixInsight Convention] System.Console.pas(352): C107 Class field name 'StdIn' should start with 'F'
[FixInsight Convention] System.Console.pas(353): C107 Class field name 'StdOut' should start with 'F'
[FixInsight Convention] System.Console.pas(354): C107 Class field name 'TextAttr' should start with 'F'
[FixInsight Warning] System.Console.pas(1001): W517 Variable 'StdIn' hides a class field, method or property
[FixInsight Warning] System.Console.pas(1168): W517 Variable 'ConsoleCursorInfo' hides a class field, method or property
[FixInsight Warning] System.Console.pas(996): W521 Return value of function 'Console.ReadKey' might be undefined
[FixInsight Warning] System.Console.pas(1352): W521 Return value of function 'Console.WriteString' might be undefined
[FixInsight Optimization] System.Console.pas(1023): O801 CONST missing for unmodified string parameter 'aCaller'
