lib/sql_io.py: put_table(): Calling wrapper function: adding pkey or index on the resulting table: don't display warning if a pkey can't be added, because this is actually a legitimate situation when the called function is set-returning and can return multiple rows for one input. having this as a warning results in spurious warnings in the automated tests (which look confusingly like ignored errors because Python warnings include debugging context information). e.g. `make inputs/Madidi/IndividualObservation/test.by_col.xml` causes this error in the sourcelist->sourcename splitting step (which of course can produce multiple specimenholder institutions)....

bugfix: lib/sql.py: parse_exception(): typed_name_re (used by MissingCastException, etc.): don't require "" around the value, because function names in "function does not exist" exceptions are (now?) output without them. this exception did not occur in the last import, but does occur in the automated testing and when running the associated query in pgAdmin (in both Linux and Mac OS X).

bugfix: /Makefile: apache-Linux: use the standard apt-get syntax for Makefiles (`-sudo apt-get --yes install`) instead of just `apt-get install`

/Makefile: added Apache 2.4 installation

lib/util.sh: added join ()

inputs/VegBIEN/TWiki/data/TWiki/TinyMCEPlugin.txt: twikibuttons_formats: added blockquote format

inputs/VegBIEN/TWiki/data/TWiki/TinyMCEPlugin.txt: set inline_styles to false so that markup formatting (underline, strikethrough) gets formatted using HTML tags (<strike>, etc.) instead of CSS styles ("text-decoration: line-through", etc.)
