New editor for table fields used

Merge remote-tracking branch 'upstream/master'
use conventional util name and update koreader-base
remove template pot and translated po files in the main repo
aternatively the resource file(pot file) in Transifex is updated
with `make pot` and the translated files(po files) is updated with
`make po`. `make pot po` will be handled automatically on the nightly
build machine.
remove too verbose information that is utterly untranslatable
I would suggest when creating a translate string you'd better keep
as much words together as you can other than trying to call the
`_` function on each word which may cause the final
translation in some languages unreadable.
For example, no matter how we translate the single words, the Chinese
translation of
```
_("No ") .. some_thing .. _("found ") .. _("matching") .. other_thing
```
will be nonsense.
Better way would be:
```
some_thing .. " is not found matching" .. other_thing
```
