samba36: disable dnsupdate

This fixes a compilation issue with addns. DNS updates are only used
by Active Directory, which is already disabled.

samba36: disable dnsupdate
Bumped revision to beta 2
samba36: Enable libiconv support
sambaclient: Link with iconv when using modern Samba
samba36: clean multi.o
samba36: for consistency, move it at the start of the line
samba36: also clean auth/*.o objects
webui: Added logo to the header banner
samba36: added missing talloc frame handling to smbpasswd; use a copy of the pasw when manipulating it
Update .gitignore
miniupnpd updated to Git 20141023 snapshot
minidlna: Staticly link with a precompiled libsqlite3 that has safe threading enabled, so BWDPI can continue using the shared, non-thread safe build.

This is hopefully a temporary fix until Asus resolves the threading compatibility issue with BWDPI (hoping that it actually can be resolved)
rc: Reverted NTP code to 2678 as a few users had issues with the newer code, and I can't reproduce the problem
minidlna: provide separate ARM and MIPS prebuilt libsqlite3
dropbear: Updated to 2014.66
Updated documentation
Remove border around image in MSIE 10 and lower (MSIE 11 has no border, which is consistent with other browsers)
Remove obsolete build setting from RT-AC56 profile
webui: When building the disk's partition list, also include unmounted partitions in the object's array, otherwise any indexed reference will be wrong since the webui's tree list takes into account all existing partitions, not just mounted ones.

Without this change, disks with unknown/unmounted partitions will generate an error when trying to edit sharing permissions.
For example, if partition 0 is unmounted (EFI, for example) and partition 1 contains the NTFS filesystem, selecting the first
permissions will make the webui try to access the second index entry - which wouldn't exist if we had skipped unmounted partitions
when building our newDisk.partition[] array.

The current fix is more a workaround, as the real issue lies in the actual design itself.

This issue was introduced with Asus' disk management rewrite in GPL 2769.
