month name unenclosed by braces is fine for BibTeX but results in "undefinedString" error

[cpbl]

The following fails with "UndefinedString": 'jul':

import bibtexparser

ss="""
@inproceedings{tmp,
	title = {Comparison of the accuracy of {OpenStreetMap} for {Ireland} with {Google} {Maps} and {Bing} {Maps}},
	author = {Ciepluch, Blalej and Jacob, Ricky and Mooney, Peter and Winstanley, Adam},
	month = jul,
	year = {2010},
}
"""

with open('test.foo', 'w') as bibfile:
    bibfile.write(ss)


with open('test.foo') as bibtex_file:
    bib_database = bibtexparser.load(bibtex_file)

print(bib_database.entries)

It might not be a bug but a hidden feature XD. Guess this should be added to the documentation.

The default parser used in the load method has its parameter common_strings disabled. To enable it change your script the following way. Also, I think this parameter should be True by default.

add:

from bibtexparser.bparser import BibTexParser

change:
bib_database = bibtexparser.load(bibtex_file)

to:
bib_database = bibtexparser.load(bibtex_file, BibTexParser(common_strings = True))

I agree this should be the default.
