Extension of the default output file of the "Filter BAM/SAM files" workflow element and other issues

Scenario:

1. Open the Workflow Designer.
2. Create the following workflow: "Read File URL(s) > Filter BAM/SAM files".
3. Select the "Read File URL(s)" element, add an appropriate input SAM or BAM file.
4. Select the "Filter BAM/SAM files" element. Set "Output format" to "sam".
5. Run the workflow.
   Current result: the output file name is generated based on the input file name as follows: "filename.filtered.bam". Here filename also contains the input file extension.
   Expected result: TODO

The following should be fixed:

1. Rename the element from "Filter BAM/SAM files" to "Filter BAM/SAM Files" ('F' character should be uppercase).
2. Correct the list of values of the "Output format" parameter. The values should be uppercase: SAM, BAM.
3. Correct the output file extension in case of "SAM" output format (see the scenario above).
