AjaxFileUploadServlet - change default setting

[rsoika]

change default setting to 10 MB filesize
currently setting of 100MB makes no sense

[rsoika]

Overwrting is possible with the following web.xml setting. - need to be documented

	<!-- Fileupload servlet -->
	<servlet>
		<servlet-name>FileuploadServlet</servlet-name>
		<servlet-class>org.imixs.workflow.faces.fileupload.AjaxFileUploadServlet</servlet-class>
		<load-on-startup>0</load-on-startup>		
		<multipart-config>
	      <location>/tmp</location>
	      <max-file-size>5242880</max-file-size>
	      <max-request-size>5242880</max-request-size>
	      <file-size-threshold>1048576</file-size-threshold>
		</multipart-config>
	</servlet>
	<servlet-mapping>
		<servlet-name>FileuploadServlet</servlet-name>
