Mobile Gmail should use 100 kB less memory

Previously, string results from WebSQL were always 16 bit strings even if they
could fit into 8 bit strings. This CL tries to create 8 bit strings from sqlite
results when possible.

This CL halves the total number of 16 bit strings retained by Mobile Gmail. It
doesn't halve the total memory used by 16 bit strings, however, because there
appears to be another source of 16 bit strings that tend to be longer on
average. Even so, this CL appears to be worth about 100 kB of memory.
