New option: g:startify_mapping_nowait

This option forces the use of <nowait> mappings.

This might be useful if you have global mappings that start with the same
characters as indexes from Startify.

References #180
Closes #186.

+This helps guarding against global mappings that start with the same
+characters as a Startify index, but might break local mappings, e.g. when you
+have indexes "1" and "11", the "11" won't be accessable anymore, since "1"
+will be opened right way.
+
+Only use this when you know what you're doing.
