[Pas2js] compileserver bug

[Tomislav Avramovic]

Can you add this to httpcompile.pp after line 494

{$ifdef unix}
   MimeTypesFile:='/etc/mime.types';
// add
{$else}
   MimeTypesFile:=ExtractFilePath(System.ParamStr(0))+'mime.types';
// end
{$endif}

On Win without mime.types file Chrome open SaveAs dialog when you open 
html file because content-type is octet.
Also add some notes for developers to add mime.types file with 
compileserver.exe
if
   MimeTypesFile:='mime.types';
then we must put mime.files file in every project dir.
