    Add support for wide translation tables for window tool furniture · cd1be707

    With the introduction of 16bpp/32bpp modes it became possible to request tables from ColourTrans which used > 1 byte per colour, but the Wimp wasn't using this extension. Therefore tool sprites designed in 8bpp or less would be quantised horribly when plotted in a 16bpp or 32bpp mode.
    The Wimp now requests and plots with a wide table, and to avoid thrashing ColourTrans so much with the prevalence of individually paletted icon sprites, keeps the table seperately to the icon sprites ones. At worst (in 32bpp) this uses an extra 256x4 bytes of RAM.
    Trace.s: Split out the tracing routines from Wimp10 as it was getting a bit big.
    Tiling.s: Namespace change for the icons versus tools distinction. Removed some unnecessary PC+8/PC+12 confused NOPs.
    Tiling3D.s: Namespace change for the icons versus tools distinction.
    Wimp01.s: New set of variables to track the tool translation tables separately. Various jiggling to keep ADRs in range.
    Wimp02.s: Namespace change. Remove some double handling in Wimp_SetColourMapping.
    Wimp04.s: Namespace change. Made factor rationalisation common to both the icon and tool grinding code. Removed dual use of cachespritedata for both icons and tools. The tintfunc moves to Wimp10. Service_InvalidateCache confusion resolved by adding a new flag to remember that the tools need regenerating rather than just marking the tool list as missing (which subsequently got restored in Tool_SpriteOp without actually doing any palette work.
    Wimp10.s: Label tools_area renamed as it was immensely confusing to have that (which was actually holding the RMA allocation of the tool_list) and tool_area (which contains the sprite area) hanging around. Changed references to use tools-only cachetolspritedata routine. Added 'wide' flags to sprite op and colour trans calls. Tool_SpriteOp changed to actually regenerate the colour tables when they're known invalid (previously the tools list pointer was merely restored and no colour tables used). Trace functions extracted. Resolved confusion as to what recache_tools_trans and recache_tools_trans2 should be doing.
    Tested with 4bpp "NewLook" sprites in 4bpp/8bpp/16bpp/32bpp and 8bpp smooth greyscaled "Steel" tool sprites in same modes.
    Also ran a task window doing repeated Service_InvalidateCache calls while monitoring the RMA for leaks.
    Generally navigated around some directories to ensure that inverse icons (during double click) and filer windows (with individually paletted sprites) were being rendered.
