BioFetch.pm: Close first the filehandle and then test for a throw,
or the filehandle will remain open and block temporary file deletion
WebDBSeqI.pm: Close a filehandle from an object that
is not going to be used anymore, which was blocking file deletion
MeSH.pm: A possible format change in the html content broke
the parsing. The code was expecting just "<TD>" and found
"<TD colspan=1>", so changed the regex to be more flexible
(<TD(?: [^>]+)?>). Also added some cleanings to $desc
MeSH.t: Updated test to expect the current description of D012851
HTTPget.t: Fixed a "bareword not allowed" error
Consed.t: Removed the exclusion of Windows from the test file
since all tests pass fine
