Updates for normal task EXT-6267 ([TRUNCATION] [EN XUI REWORK] - Side panel, profiles: the teleport button is truncated. need 'en' xui designer rework)
* 'en/panel_profile.xml' was redesigned. Assuming that 'de' locale doesn't have width overridden:
 ** added ellipses to buttons' labels to get possibility found truncation easier (except for IM button)
 ** reduced distance between buttons
 ** reduced padding from left/right sides to 1 px

But there are still issue in two locales:
'es' for "add friend"
'pt' for "teleport"
These buttons can not be shown properly with default widths.

Note: 'de' & 'fr' locales have overridden width (not removed in the patch)
