Summary

Remove DocName from applications:

• Remove data member from WrapperApplication class, remove getters/setters from C++ and python APIs.
• Remove SetDocName from all applications
• Show only Name in documentation
• Remove column from GUI application browser
• Fix python API Application.__str__()

Rationale

For 95% of OTB applications, the extra doc name is useless. Except for maybe those three applications:

LSMSSegmentation                        Exact Large-Scale Mean-Shift segmentation, step 2
LSMSSmallRegionsMerging                 Exact Large-Scale Mean-Shift segmentation, step 3 (optional)
LSMSVectorization                       Exact Large-Scale Mean-Shift segmentation, step 4

the DocNames are same as the normal Names, but with spaces, casing and word order changed. The DocName adds nothing to the normal Name. Additionally it can be confusing for users when mixing cli/gui interfaces and reading documentation.

For simplification I propose to remove it, but we could also add a dummy implementation of GetDocName/SetDocName that does nothing, to improve backwards compatibility with < 7.x.

Closes #1789 (closed).
