nifti files are stored under mincpath

I noticed while reviewing #4096 that .nii and .nii.gz files are both using the mincPath configuration setting for the location to store them.

This makes the configuration name confusing and should probably be cleaned up.

@driusan Looking at the Config paths, there is a lot of redundancy and I think this could be cleaned up: mincPath = data = imagePath = dataDirBasepath

• imagePath used by get_file.php, tool generate_project_statistics_csv.php, php/installer/Installer.class.inc, mri_violations.class.inc, API 0.0.2 and 0.0.3-dev (candidates/visits/images/format/Thumbnail.php) and imaging_install.sh
• data does not appear to be used anywhere in the LORIS code...
• mincPath used by php/installer/Installer.class.inc, brainbrowser image.php, get_file.php, API 0.0.2 and 0.0.3-dev (candidates/visits/images/Image.php) and imaging_install.sh
• dataDirBasepath used by the imaging pipelines (under section Imaging Pipeline)

Will bring it up at the next Imaging meeting so we can decide as a group what to do with it but we should probably just use the imagePath one.

Discussed during the LORIS-MRI meeting of January 18th. Will keep only the dataDirBasepath field in the Config module
