Merges/treats Morphic-ct.1681, but emphasize the need to use text attributes properly. We must style the text contents via text attributes, both color and font. We must not rely on TextMorph internals such as how #textColor: is used by default. For example, TextMorph >> #font: behaves very differently in this regard.
***
Morphic-ct.1681:
Fixes use of custom attributes in DialogWindows
Things like the following did NOT work properly before this patch:
self inform: 'normal ' asText
, ('red ' asText addAttribute: TextColor red; yourself)
, ('font ' asText addAttribute: (TextFontReference toFont: ((TextStyle named: 'BitstreamVeraSansMono') fontOfSize: 20)); yourself)
, ('url ' asText addAttribute: TextURL new; yourself)
This was because DialogWindow added its own styling attributes on top of all existing attributes. For color, this is not necessary because #textColor: is sufficient. For font size, in theory, TextFontChange should be sufficient, but currently it does not support relative changes to the font size.

Makes it possible to specify a different default base in number parsers. There is no need to hard-code the 10 and I am actually building something with a different default number system. Clients can still change the base via the radix notation.

defaultBase: 16;

(ExtendedNumberParser on: '2r10')
defaultBase: 16;

Also adds Integer class >> #readFrom:base:ifFail: for convenience. Removes redundant class-side overrides on SqNumberParser.

NumberParser is an abstract class for parsing and building numbers from string/stream.
It offers a framework with utility methods and exception handling.
Number syntax is not defined and should be subclassResponsibility.
Instance variables:
sourceStream <Stream> the stream of characters from which the number is read
base <Integer> the radix in which to interpret digits
neg <Boolean> true in case of minus sign
integerPart <Integer> the integer part of the number
fractionPart <Integer> the fraction part of the number if any
exponent <Integer> the exponent used in scientific notation if any
scale <Integer> the scale used in case of ScaledDecimal number if any
nDigits <Integer> number of digits read to form an Integer
lasNonZero <Integer> position of last non zero digit, starting at 1 from left, 0 if all digits are zero
requestor <TextEditor | nil> can be used to insert an error message in the requestor
failBlock <BlockClosure> Block to execute whenever an error occurs.
The fail block can have 0, 1 or 2 arguments (errorString and source position)
+ defaultBase <Integer> the default radix in which to interpret digits, unless specified differently via radix notation!
