scripts that WERE updated && notes:

abundance-dist			already does earlier in script
abundance-dist-single		already does earlier in script
count-overlap
extract-long-sequences
extract-paried-reads 		explicitly two output files; listed on one line:
				print('wrote to: ' + outfile + '.se' + ' and ' + outfile + '.pe')
fastq-to-fasta			file output optional; either outputs 'wrote to' message or 'did not write output to file'
filter-abund-single		already does earlier in script
interleave-reads		file output optional; either outputs 'wrote to' message or 'did not write output to file'
load-graph
load-into-counting		creates various partway files, messages for them already exists.
				'wrote to: ' message only prints on successful program end to ensure being printed
				at the end of output.
make-initial-stoptags		uncertain how output is written since script uses "htable.save_stop_tags()" instead
				of explicit file write object. 'wrote out: ' message added anyway.
merge-partitions		No API entry exists for this script!
				Already messages earlier in script
partition-graph			threading is confusing; potentially multiple files
split-paired-reads		explicitly two output files; message is:
				"'wrote to: ' + out1 + ' and ' + out2"

scripts that were NOT updated && notes on why:

annotate-partitions 		already does, multiple files
count-median 			already does
do-partition 			already does, multiple files
extract-paritions		already does, multiple files
filter-abund			already does, multiple files
filter-stoptags			already does, multiple files
find-knots			already does (mostly), multiple files, renames some things without outputting message
normalize-by-median		personally uncertain about logic flow && script appears to warn on output anyway
sample-reads-randomly		already does, multiple files
refactored scripts/fastq-to-fasta.py as per CTB instructions; set write_out to sys.stdout by default and cleaned up output file listing
Removed redundant file listings. Adjusted spacing.
fixed broken interleave-reads.py testing; now detects if outputting to file or stdout and lists as such.
fixed induced brokenness to fastq-to-fasta due to inattention in editor management.
Adjusted formatting to comply to pep8 standards.
Updated changelog to reflect earlier changes
Attempting to resolve optional file issue; primarily commiting to get Jenkins to test.
Fixed interleave-reads.py's optional file issue.
updated load-graph.py output listing to list all files written to. Also updated print statement to write to sys.stderr and to conform to python2 format.
Syntax is a learning experience.
:Fixed Changelog Conflicts.
Added test for scripts/make-initial-stoptags.py
Updated output file listing to write to sys.stderr (imported sys as well)
Generated files for testing
Fixed formatting errors
Changed output listing print statements to print to sys.stderr
Refactored fastaq-to-fasta.py to default output to sys.stdout

Updated interleave-reads output listing to point to the proper place

refactored load-graph output listing to drop an else clause
(may have blatantly copied from mr-c here)

removed debug string from abundance-dist that somehow made it into
the last commit

refactored make-initial-stoptags test generate test data from
load-graph.py to reduce payload size of test_data directory
note: this assumes load-graph will work
removed some extraneous files in the test-data directory after
refactoring make-initial-stoptags test

Fixed pep8 formatting issues

Fixed argparse documentation formatting issues in fasta-to-fastq.py
Refactored things that made it through the cracks in fastaq-to-fasta.py
updated changelog entry to no longer include nonexistent files.
Merge pull request #596 from bocajnotnef/lowhangingfruit/script-output-file-listing

Resolved issue #577 (mostly); most scripts output filenames written to at end of main
Run autopep8
Merge with master
