[MOD][TWEAKS][SCRIPTS] XTweaks V2.0 (08-27-2014)

XTweaks is a script pack similar to others availables on XDA BUT with some of the logic from
SuperCharger V6 by zeppelinrox
(automatically set some values based on your total available RAM because not everybody have the same device isn't it?).
I've been using this scripts in my custom roms and it worked very well, so I decided to release it to public.

V2.1
- Another fix on SQlite binary installation (hopefully now will install on every device without problems).
- Now the Bootanimation is optional (in consequence the mod was reduced to about half of the size, benefiting to devices with low system partition size).
- Now you can uninstall/install (installed by default) Entropy-ness script (if you preffer to install an entropy generator binary) typing:

Code:

su
entropyness

- Added adj's values to RAM script.
- Added more governors to CPU script.
- Small changes/fixes on some scripts.

V2.0
- New way to install SQlite binary (some devices was having problems on the "old" installer way).
- Some changes in the main installer (you can flash it on top of the old versions).
- A few changes in the "check" script.
- Deleted 00Buildprop script and changed by 01SetProp (some devices/ROMS doesn't ran the 00Buildprop script in consequence the values doesn't applied to build.prop, now the 01SetProp script applies those values with the "setprop" command).
- Now all the scripts will run until the system fully boots.
- Now the RAM manager script will set the lowmemorykiller parameters based on your total available RAM (balanced values).
- Now you can see all the changed parameters in the logs (Maybe you will see some errors and are caused because your ROM doesn't support those changes, just ignore it).
- Minor changes on some scripts.
- Renamed all the scripts (small changes).

V1.0.2
- Added check script
- Renamed uninstallboot script to restoreboot

V1.0.1
- Fixed "permission denied" on uninstallboot script
- The integrated Bootanimation will install only on ROMS where
/system/media/bootanimation.zip is persent to prevent issues
related to Bootanimation.
