Escape mappings that use '<>' notation.

Browse Source 
KeyMap.bind() does not gracefully handle use of '<>' notation.  For
example, trying to call NERDTreeAddKeyMap() with a 'key' argument of
'<Leader>e'.  There were some workarounds KeyMap.bind() to help with
this by specifically allowing you to leave off the '<>' parts for
'<C-...>', '<M-...>' and mouse mappings and it would add them back for
you before creating the mapping.  This commit reverts some of that logic
and simply says that if the key starts with '<', replace it with <lt>.
