Two hardcoded spaces on configuration page

[Alexander Obuhovich]

In-Portal has 2 types of configuration variables:

• ones, that are displayed separately (1 variable at a row)
• ones, that are displayed in pairs (2 variables at a row, like "sort field", "sort direction") 

Problem is, that there are "  " hardcoded in thaat 2 variable-per-row block design, that are preventing any custom row design to be applied.

In particular without attached patch being applied task: http://tracker.in-portal.org/view.php?id=1086 looks weird, like "[min_value]   - [max_value]" instead of "[min_value] - [max_value]".

Task: http://tracker.in-portal.org/view.php?id=1096

Ready for testing.
