Release notes

This release adds some internal changes to MOS with the aim of making it more stable and reliable, and laying some building blocks for the future. There's a few new commands too!

Much of the original groundwork for this release was done by @envenomator - many thanks! @tomm built on Jeroen's work, and also added in some new safety features, such as blanking memory on a fresh boot and adding in a RST 038h handler which will can provide a "crash" report when a program misbehaves. There's also a filing system bug fix from @lennart-benschop to ensure that files are written with correct dates.

This version adds three new star commands to MOS, and two new APIs:

• *mem will show a report on system memory usage and availability
• *echo provides an "echo" command in the style of the Echo command on RISC OS
• *printf provides a more unix-style "echo" command
• RST 38h prints a crash report, which works in conjunction with memory being reset to 0xFF on boot to guard against execution of uninitialised memory
• ffs_api_ftruncate has been implemented which allows files to be truncated
