#48 BibTex errors are not honored in logfile error analysis

[Wolf-Gideon Bleek]

When compiling latex files with bibtex citations
ecleTex performs two compiler runs with a bibtex run
inbetween. Errors during the bibtex run are discarded
because that logfile is not analysed. This makes it
hard to find errors related to bibtex, e.g. a missing
bibtex-style-file or errors in the bibentry specification.

A possible solution could be to rename the logfile
after the bibtex run to have it available for logfile
analysis afterwards and do the analysis for both files.
