Avoid harmless signed/unsigned warning in g++ 5.4 wxGTK build

Browse Source 
Change GTKGetEntryTextLength() to return a signed value, as it's always
either assigned to or compared with the signed variables anyhow.

This avoids a couple of -Wsign-compare warnings when building with g++
5.4 from Ubuntu 16.04.
