metadata error in bounds

[ealaz]

The metadata does not result in a valid xml file. Most codes will tolerate this but some (Garmin Homeport) will not, TYhe error is in bounds which has added space (linefeed). It can be corrected by modifying gpxfield.py as follows to remove the offending space & linefeed.
if tag:
if tag == 'bounds':
if tag_open:
body.append('>')
body.append('</' + tag + '>')
#print("tag,body:",tag,'\t',body)
else:
if tag_open:
body.append('>')
body.append('\n' + indent + '</' + tag + '>')
It is inelegant but it works.
