Revert "Mer: Adde Mer welcome page to translations"

Seems useless. kaltsi verified - thanks.

This reverts commit 1ca81158abf03d7cf82a0f5308466c1aec534049.
Merge branch 'mer-3.1' into next

Notes
 - Compiles w/o error; did not try to execute
 - dist/gdb/ resolved by resetting to next, i.e., kept our version which
   also matches Mer version
 - src/tools/sdktool/ resolved by resetting to mer-3.1, i.e.,
   temporarily throwing out our changes - will be rewritten later.
