trim filename in webfrontend for windows compatibility

[aignerat]

Added trim function in javascript to ensure compatibility with windows

scenario: I create the file "test.txt " and can't synchronize it with my local file-base. The same issue happens with folders with whitespaces at the begin or end. This feature ensures that a windows-user can't create the same circumstance for himself accidentally.
