 Compiling my wx-related code with gcc-4.3.x gives massive numbers of
 warnings about the inclusion of deprecated headers. The culprits are
 wx/hashmap.h and wx/hashset.h, which includes hash_map and hash_set.

 The attached patch solves this problem by:

 1) adding configure checks for the availability of <tr1/unordered_map>,
 <tr1/unordered_set>. It adds (conditionally) #defines HAVE_TR1_HASH_MAP,
 HAVE_TR1_HASH_SET to config.h
 2) when these are available, these are used instead of the non-standard
 hash_map, hash_set.

 In the (near?) future, we will need additional checks for <unordered_map>,
 <unordered_set>. The present patch anticipates these changes by using
 additional indirection:it introduces additional defines HAVE_UNSORTED_MAP,
 HAVE_UNSORTED_SET in the relevant header files, similar to what was
 already done for hash_map, hash_set.

 The patch was tested with an STL-enabled build on Linux/GTK.

 When verified, please apply: the amount of warning messages is horrible,
 and we wish to avoid-fno-deprecated. Thanks!
