remove edje file changed monitoring as it's nothing but a bug vector

so this has to go. reloading edje files is nothing but trouble.
example - if you update your os your theme files get updated and then
all sorts of stuff goes wrong. jeff is right. this makes it an
intractible problem. we have an open file handle on the edj file. we
share that anre reuse it via eina_file - keep it. this keeps tyhe edje
file stable and consistant.

<Jef91> Elementary applications freak the fuck out
<Jef91> if you change the theme file
<Jef91> that they are using
<Jef91> SeoZ,

<Jef91> that happens when my theme file that is in use changes

we will get nothing but continued issues and complains if we keep
doing this. it's a fairly pointless mis-feature. thank god its got no
apis - just signals and internals.
