Add configUSE_MINI_LIST_ITEM configuration option to enable the MiniListItem_t type. (#433)

Browse source 
* Add configUSE_MINI_LIST_ITEM configuration option to enable the MiniListItem_t type.

When configUSE_MINI_LIST_ITEM == 0:
	MiniListItem_t and ListItem_t are both typedefs of struct xLIST_ITEM.

When configUSE_MINI_LIST_ITEM == 1 (the default in projdefs.h):
	MiniListItem_t is a typedef of struct xMINI_LIST_ITEM, which contains 3 fewer fields than a struct xLIST_ITEM.
	This configuration saves approximately sizeof(TickType_t) + 2 * sizeof( void * ) bytes of ram, however it also violates strict aliasing rules which some compilers depend on for optimization.

configUSE_MINI_LIST_ITEM defaults to 1 when not defined.

* Add pp_indent_brace option to uncrustify config

Improves compliance with the FreeRTOS code style guide:
