Travis update attempt
#changes
2.0.15
use test not [ ]
Quote TRAVIS_OS_NAME that doesn't always seem to be defined
do not change "( )" to "rdf:nil"

In tests/turtle:
rapper -i turtle -o turtle test-08.ttl
changes "( )" to "rdf:nil".
This change to src/raptor_serialize_turtle.c will produce "( )" in the
output file.
Looks like Travis OS support is not generally available

sudo
delete working dir
run autogen.sh not configure twice
Make process-changes.pl report wrong fields count
Rename changes file to raptor-changes.tsv

Not just about v1 to v2
add tests for rdf-nil

test-08.ttl is valid test, but output is not saved => no change
for test of exact syntax, add files test-39.ttl and test-39-out.ttl
modify Makefile.am for these two new files
non staged changes are just dos2unix conversions
Merge pull request #16 from rhmccullough/rdf-nil

do not change "( )" to "rdf:nil"
Accept '_' as alias/typo for '-' in lang strings. Replace on parsing.

Remove raptor_turtle_check_uri_string() which is at wrong level.

Needs to be checked in earlier lexing so e.g. illegal escapes in URIs
such as \b are found.  For example.
