Delimited text provider indexing implemented.

Efficiency improvements.

Adds capabilities
   SelectAtId
   CreateSpatialIndex

This uses line number as an index.  Allows jumping to a line number
without interpreting all intermediate records, so much more efficient.
Also retains the current record in a buffer, so successive requests for
the same record do not require rereading the file.

With index available have also added indexing of subsets and optional
creation of spatial index.

Note: did try using QTextStream.pos to build a random access index -
this was incredibly slow.  Have found using line based index is
reasonably fast even on quite large (50+Mb) text files.
