e2419ece0b Added scrcode macro for the Apple II. 
Although the Apple II generally works with plain ASCII (i.e. in the ProDOS 8 MLI) the actual screen codes differ. This fixes #260.

67cd0c2197 Added .asize and .isize pseudo variables 
These pseudo variables will return the size of the accumulator/index
in bits.

For the 65816 instruction set .ASIZE/.ISIZE will return either 8 or 16,
depending on the current size of the operand in immediate addressing
mode.

For all other CPU instruction sets, .ASIZE/.ISIZE will always return 8.

For example:

	; Reverse Subtract with Accumulator
	; A = memory - A
	.macro rsb param
		.if .asize = 8
			eor	#$ff
		.else
			eor	#$ffff
		.endif
		sec
		adc	param
	.endmacro

2c975d3642 Create static drivers directly from source files. 
Up to now static drivers were created via co65 from dynamic drivers. However there was an issue with that approach:

The dynamic drivers are "o65 simple files" which obligates that they start with the 'code' segment. However dynamic drivers need to start with the module header - which is written to. For dynamic drivers this isn't more than a conceptual issue because they are always contain a 'data' segment and may therefore only be loaded into writable memory.

However when dynamic drivers are converted to static drivers using co65 then that issue becomes a real problem as then the 'code' segment may end up in non-writable memory - and thus writing to the module header fails.

Instead of changing the way dynamic drivers work I opted to rather make static driver creation totally independent from dynamic drivers. This allows to place the module header in the 'data' segment (see 'module.mac').

bb9aa7558f Fixed the SGML <htmlurl> and <url> tags. 
Those tags have two attributes: "url=" and "name=".  In the non-HTML output formats, <url> shows both fields, while <htmlurl> shows only the name field (as the HTML format always does.)  Thus, the general rules are
1. If the two attributes are different, then use <url>.
2. If they are similar, then use <htmlurl>.
3. If they are the same, then consider using <url> without the "name=" attribute.
(The reason for rules 2 and 3 is that the same text shouldn't be shown twice.)

There can be exceptions.  Example: "od65.sgml" has <htmlurl> because the URL
would disturb the flow of a sentence.
