An early draft; dealing with the issue that not all cycles are necessarily consumed in a single call. Incomplete; broken. Committing for cross-machine visibility.

Introduced the ability simply to piggy-back off the CRT's natural phase for the colour burst, thereby eliminating a couple of redundant independent attempts in the Oric and Electron.

Merge pull request #83 from TomHarte/InterruptLine

Deintegrated the busy flag and the interrupt request line, as the latter is reset by status reads. Which also means I can start reporting the WD INTRQ line status directly from the Microdisc. That appears to be correct, rather than honouring the Microdisc IRQ select there.

Made an attempt to shuffle the texture builder to a similar flush/submit pattern as the input builder. Don't care about thread safety yet, as it's obvious I'm going to need to move that back up to the CRT.

The remainder of this test isn't necessarily safe to perform if the array length isn't as expected. But in that case the test has already failed, so it's not worth worrying about a partial validation.
