Bring back the VignetteBuilder in dev
pagerResources will give total record numbers

When calling `list*`, there will be a message with the total number of
objects found. `pagerResources` defaults to the paging parameters fixed
server-size (bins of 20 records), so the queries are not *too* heavy.
Documentation for mangalList

Added an entry in the parameters for `filtering`.
stringr is now used throughout
Fixed a bug in whatIs

jsonlite passed the choices as a list, which caused str_c to crash
Re. #19 -- client=rmangal

Also changes to the way filtering is done.
Version bump to 0.4.0 because of slight API changes.
Update to the vignette on filtering
Owner field is not updated when resources are patched
Keep owner name when patching
DESCR
Sort the columns of taxa_table (#22)

For some reason, the `id` column is not necessarily the first one in the
data table for taxa when exporting to igraph. This can cause duplicated
vertex errors.

It would be oh so simple if igraph stopped thinking about positions in
the data.frames and LOOKED AT THE DAMN NAMES.
