Quick fix!!

Another hiccup caused by fastqc update, guess its better to ignore the html rather than removing it ;) 
Hej!

Just a performance note; Here you're going through the list of files twice: one for listing files and the other one for excluding html files. If the number of files is big that _could_ be an issue. You can avoid that by using ```iglob``` instead of ```glob```, as it returns an [iterator](https://docs.python.org/2/library/glob.html).

```python
fastq_dirs = []
path = glob.iglob(os.path.join(analysis_dir, "fastqc",
                                          "%s_%s*" % (lane_num, fc_date)))
[fastq_dirs.append(fastq_dir) for fastq_dir in path if not fastq_dir.endswith('.html')]
```
