Changing Cell Validate Text

Hi All,
Before I push this (which I will do tomorrow). I want to get preference
opinions if possible. Here is the bug report:

https://bugs.freedesktop.org/show_bug.cgi?id=43518

I tend to agree with the complaint (although it's incredibly minor).
Technically "between" should not include the minimum and maximum numbers
put in. Since they are (and I think that this is preferred) the text should
be changed. I opted for "valid range" and "invalid range". There are other
options including:

between (inclusive) & not between (inclusive) or simply include range &
exclude range

This is really minor but I'm trying to knock off some of these little bugs
that just take a small amount of time to fix. If you're opposed to any
change in language &/or prefer different wording please respond, otherwise
I'm pushing my updates as soon as possible.

Lastly, on a technical note. What's the easiest way for me to replace all
occurrence of a variable with another name. In order to be consistent I'll
have to update the variable name along with the actual text name.

Thanks all,
Joel
