183ea8e362 Implement support for iif(). 
In sqlite, iif() looks like:

sqlite> create table iiftest(a int, b int, c int);
sqlite> explain select iif(a,b,c) from iiftest;

0597c048fc Better support for BLOBs 
- Limbo command line shell supports e.g. `SELECT x'616263';`
- `EXPLAIN SELECT x'616263';` lists the opcode

Missing:

- Command line shell not entirely compatible with SQLite when blobs have
  non-printable characters in the middle (e.g. `SELECT x'610062';`)
- Python bindings not supported (incoming soon)
