updated .bashrc

feat(bashrc): # CLEANED UPDATED BASHRC

- Hauptkonfiguration aufgeräumt und modularisiert
- History optimiert (gemeinsame History mit history -a; history -n)
- Laden ausgelagerter Dateien: ~/.bash_aliases, ~/.bash_env, ~/.bash_paths
- farbiger Prompt inkl. xterm/rxvt Fenstertitel
- dircolors integriert (LS_OPTIONS als ENV -> .bash_env)
- nützliche Shell-Optionen gesetzt (cmdhist, lithist, checkwinsize)
