[aur-general] Delete request

[Limao Luo]

I am requesting gtk-engine-pixbuf [1], fontconfig-cleratype (sic) [2], 
and thunar-thumbnailers [3] for deletion. The feature that [1] provides 
has been added to the gtk-engine itself and therefor is obsolete. [2] is 
a misspelling of fontconfig-cleartype, which is well-maintained as of 
now. [3] has been superceded by extra/tumbler, and the project itself 
hasn't been updated in over a year.
