Content, Buttons alignment, Typeface

Since my language is right to left, I've added content and buttons alignment.

CustomDialog.Builder builder = new CustomDialog.Builder(Context context, String title, String positiveText);
builder.rightToLeft(true);
//or
builder.mTitleAlignment (Alignment.RIGHT);
builder.mContentAlignment(Alignment.RIGHT);
builder.mButtonsAlignment(Alignment.LEFT);

//I've added typeface for builder too.

Typeface tf = Typeface.createFromAsset(this.getResources()
					.getAssets(), "Custom.ttf");
builder.typeFace(tf);
