Merge pull request #323 from PeterBjuhr/master

svgview first pull request, with working point-and-click and page chooser
make locating js file robust, we cant assume frescobaldi_app is in the current directory
clear page chooser before adding pages
improve layout of svg view widget items

for the forseeable time just display the filename in the pager combo. There could be more score expressions
better shortcut G, S was used already
load existing svg
just get the doc from the url, textedit links can point to different documents
mainwindow never changes, no need to set it or keep it. just get it via the parent and save it in the JSLinks object
allow the -! script abbreviation
if the document >= 2.17.25, insert -! for staccatissimo instead of -|
install the js files and put them also in sdist
just use QWebView for Svg, not a QGraphicsWebView as an item in a QGraphicsScene
Merge branch 'master' of github.com:wbsoft/frescobaldi
the SvgScene was renamed to View as it is just a QWebView
instantiate JSLink just once, name the attribute jslink
dont instantiate many identical functions
add option to set default output format

current choices are pdf or svg
tabify svgview and musicview by default
SVG=Scalable Vector Graphics
