ramdisk+AnyKernel2: synapse: add script pushing support
- allow pushing scripts to a location to function as a checkbox to enable support for including init.d/addon.d scripts
- add toggle for Custom Kernel Persistence addon.d script; allows users to retain our kernel through a delta/upgrade or dirty ROM flash.
ramdisk+AnyKernel2: synapse and bootscript updates/fixes
Synapse:
- fix minor zram control issue
- remove Multi Core Power Saving since it's always been broken on tuna, and being removed from the kernel source by Smitty

dvbootscript:
- only enable KSM by default on SmittyV
- add nobarrier to fstab, since is now supported in the kernel, and add it to userdata workarounds list for potential issues with old init binaries (barrier=0 was definitely an issue on ext4). Put them in the order output by mount command while we're at it.

Note: f2fs doesn't accept barrier=0 interchangeably with nobarrier like ext4 does.
