This patch updates ST's HAL to the latest version, V1.3.0, dated 19 June 2014. Files were copied verbatim from the ST package. Only change was to suppress compiler warning of unused variables in 4 places. A lot of the changes from ST are cosmetic: comments and white space. Some small code changes here and there, and addition of F411 header. Main code change is how SysTick interrupt is set: it now has a configuration variable to set the priority, so we no longer need to work around this (originall in system_stm32f4xx.c).
