Improved shell settings

[Pander]

Please improve default shell settings so that:

• Command history is tenfold of the current situation. Because the virtual keyboards are not as fast as normal keyboards, good history of commands is very handy. See HISTFILESIZE

• Start applications via ssh on your device more easy. See export DISPLAY=localhost:0

• interactive mode aliases for cp, rm and mv, see alias rm='rm -i'; alias cp='cp -i'; alias mv='mv -i'

• more ls aliases, see alias la='ls $LS_OPTIONS -ltrA'; alias lh='ls $LS_OPTIONS -ltrh'; alias lr='ls $LS_OPTIONS -ltr';

alias lR='ls $LS_OPTIONS -ltrR'

Having all these setting as default would increase the direct usability of the shell.
