BuildFormBootstrap: fixed typo in class id pills
QfqForm.js: rewrote logic after press 'save'

QfqPage.js: history: do not create a history entry for each tab click, instead just set the current history to the current tab, i.e. the back button won't take the user thru the tab history.

Alert.js: Click handler on message will only be installed IF no buttons are to be displayed. If buttons are displayed, the buttons will dismiss the message upon click.

BSTabs.js, PageState.js, Form.js: done.
Alert.js: first draw, layout not of alerts not proper yet.
Added jasmine tests.

PageState.js: allows to use window.history.state, which is dubbed `data`. PopState Handlers are now called with the PageState object as first and only argument, in order to allow access to `data`.
QfqPage.js: use data to store page title in page state. Constructor sets page state explicitly, if none exists so far by setting it to the active tab; this allows to navigate to the first state.

Gruntfile.js: concat and uglify for our javascript stuff.
Added support for storing state of Bootstrap pills.
Added jasmine tests.
