Laser/Laserpointer - Fix localization of laser

[Wakbub]

Add

• laser: Add missing Hungarian translation of laser (BI doesn't have it translated).

Change

• laser: Change localize to LLSTRING.

Fix

• laser: Fix capitalization of laser. It's used in settings and looks off with only "laser" but no other setting in lowercase.
• laserpointer: Fix Japanese translation of "Laser" to match the one in the laser module.

ToDo?

• The same translation of "Laser" now exists in both the laser and laserpointer modules. Maybe it should be put in common?
• "レーザー" and "レーザ" are mixed in the aforementioned modules. I guess the former should be used: a Japanese person I asked said the former is correct and the latter wrong, BI uses the former, Wikipedia redirects to the former, most dictionaries I've looked in translates "laser" to the former, but for some reason Google translates it to the latter.
