Porting scripts to KVIrc 4

This is a quick list of things you should take care of when porting kvs scripts from KVIrc 3 to KVIrc 4:

List of function names that have changed:

Old Name	New Name	Applies to
$setCaption	$setWindowTitle	widget class
$setIcon	$setwindowIcon	widget class
$setColStretch	$setColumnStretch	layout class
$setDisplayStr	$displayStr	lcd class
$setDisplayInt	$displayInt	lcd class
$setDisplayDouble	$displayDouble	lcd class
$setLayoutOrientation	$setOrientation	groupbox class
$base64ToText	$base64ToAscii

Other important changes

• The widget class does not need anymore the "Customize" flag in $setWFlags()

• The $time() function has been removed in favour of $date: echo $date("F T",$unixtime)

• objects.bitBlt has been removed. If you want to paint on a widget, you must do it in its paintEvent using a painter.

• in $str.replace the order of the 2nd and 3rd parameter has been inverted: old format: $str.replace(text, replace, search) new format: $str.replace(text, search, replace)

  This can create some bad problem with old scripts trying to trim a string using: `echo $str.replace(" the string ", "", " "); In the worst case, this will create an endless loop.

• Functions with nocase() in the end have been removed. Check their counterpart removing nocase part. Eg: $str.containsnocase("string","test") will be $str.contains("string","test",true)
