Multiple configfile-related changes - Print current configfile in the output of 'env' (this also makes configfile changeable in runtime via 'setenv') - In 'configfile' commands, print which config file is being used - Fix behavior of existing 'more_conf' - Make load_config() return filename and hash, rather than unconditionally overwrite $conf - Bring back %conf2 into implementation of save_config; it is necessary to be there or 'configfile' is getting lost/deleted in the runtime config Other changes - Add 'set' as alias for 'setenv' - Add unsetenv/unset (opposite of setenv/set) - Do not print unset/undefined values in 'env'

Support separating aliases by space too

Use local implementation of slurp()

Improve accepted command line options This commit enables getopt case sensitivity and adds all command line options/abbreviations typically supported by LDAP clients: -w/-y, -p, -x, -Z/-ZZ, -v

Support arrays/hashes in 'env' (WIP) - 'env' now prints 'attributes' array - 'env' output now supports any data type, not just strings - option --attributes on command line properly overrides config values The remaining thing to do is to support 'setenv' to work with non-strings too.

Add alias, unalias, configfile - Add commands 'alias' and 'unalias'. Behavior is almost identical to shell. Aliases currently cannot override commands. - Add command 'configfile'. Allows loading / saving config files from command line.

With ls -l, print file type ('-' or 'd') as first field of output This change brings output of 'ls -l' closer to the actual shell command.

Improve save_config()

Add missing block to Term::Shell fix (This corresponds to Term::Shell PR posted at https://github.com/shlomif/Term-Shell/pull/3)

Make aliases be auto-detected and inserted into help texts.
