[BioC] Problem loading files into limmaGUI

[Gordon Smyth]

The bug is caused by readGPRHeader() in limma assuming that certain entries 
are in the genepix header section. I have fixed the bug and it will be in 
limma 1.7.0 in a few days. The use of readGPRHeader() was introduced in 
limma 1.6.12 to solve a problem previously seen where different gpr files 
have different numbers of header records.
