Fixes #37 with other default locale than english

Test in error with french default Locale:
org.junit.ComparisonFailure: expected:<[ne peut pas être vide]> but was:<[may not be empty]>
	at org.junit.Assert.assertEquals(Assert.java:115)
	at org.junit.Assert.assertEquals(Assert.java:144)
	at org.springframework.samples.petclinic.model.ValidatorTests.emptyFirstName(ValidatorTests.java:39)

adding explicit reference to default profile because it doesn't seem to work on on some environments

Spring MVC should server static resources (*.html, ...) located in src/main/webapp instead of returning "404 Not Found"

pom:xml: use <dependencyManagement> to force versions of spring-core, spring-context and spring-beans

pom:xml: use <dependencyManagement> to force versions of spring-core, spring-context and spring-beans to 3.2.x. instead of exclusions on spring-data-jpa dependency because Maven sometimes pulls both versions 3.2.x and 3.1.x versions of coring-core, spring-beans and spring-context.
