String literals are being parsed, compiled and printed, read more

Strings, due to their potentially large size, are stored outside of a
routine's code section, in the data section. To access the correct
string, you must read the jump index, then the real address from the
jump table - and extra layer of indirection will result in more flexible
data down the road, I hope.

Other changes include:

* Added string concat operator ..
* Added TOY_STRING_MAX_LENGTH
* Strings can't be created or concatenated longer than the max length
* The parser will display a warning if the bucket is too small for a
  string at max length, but it will continue
* Added TOY_BUCKET_IDEAL to correspend with max string length
* The bucket now allocates an address that is 4-byte aligned
* Fixed missing entries in the parser rule table
* Corrected some failing TOY_BITNESS tests
