Extract str.asm from core.asm and make core included by userspace Most of register fiddling routines (which is now the only thing contained in care.asm) are used by almost all userspace apps, often in inner loops. That makes the penalty of using jump tables for those a bit too high. Moreover, it burdens jump tables needlessly. Because this unit is very small (now that string routines are out), it makes sense to always include it in binaries.

lib/parse: decimal ending with a whitespace are now valid Also, make empty strings be parsed as invalid by parseDecimal.

basic: add a print cmd It can only print a decimal literal. But still, that's a big step because I hadn't implemented decimal formatting yet.

Modify userspace .org and RAMSTART expectations Instead of expecting a `USER_CODE` symbol to be set, we expect `.org` to be set in all userspace glue code. This gives us more flexibility with regards to how we manage that. Moreover, instead of making `USER_RAMSTART` mandatory, we make it default to the end of the binary, which is adequate in a majority of cases. Will be useful for my upcoming mega-commit... :)
