Finishes the Turkish translation of six modules and removes their
machine-generated lang/tr.auto files:
useradmin 110 new strings - SSH keys, group batch files, export
quota 111 new strings - Btrfs subvolume quotas, mass updates
heartbeat 98 strings - Heartbeat cluster monitor
ppp-client 98 strings - WvDial dialup client
webminlog 96 new strings - action search, rollback, notification
ldap-useradmin 94 new strings - LDAP users, Samba and IMAP options
Also fixes five defects in the existing Turkish files:
quota/gfilesys_all was missing its $1 placeholder
quota/lusers_noquota was missing $1 and the <tt> tags
quota/lusers_info was missing $1
useradmin/batch_emove was missing $2
useradmin/export_eopen had a literal $! where $1 was meant
