Shorten text of buttons to load/edit drawn map and make them look nicer

#!/bin/sh -
# Script to update all Lua locale files.
# It's Clunky and slow!
# Note this script may sooner or later be phased out when we move to Gettext.

# HOW TO USE:
# - Run this script in the tools/ directory.
# - (Optional) Change LOCALEFILES below to limit the number of locale files to update
# Result: All .lua files in share/hedgewars/Data/Locale will be updated.

# SETTINGS:
# Space-separated list of locale files to update, or *.lua for all.
# (Note: always include stub.lua)
LOCALEFILES="*.lua"

# END OF SETTINGS

# List of all Lua files to scan:
# * Missions
# * Campaign missions
# * Lua libraries
# * Styles (aka multiplayer scripts)
# * Mission maps
# IMPORTANT: Don't forget to update this list when new places for Lua
#            directories have been added!
