Fix for file tab display issues in Chrome #60
Previously in Chrome, filenames would wrap onto a new line creating an additional vertical scroll bar in the file tab display. Additionally, the filename would wrap the close button below the tab which gives the appearance of a missing close button. Both issues have been mitigated by wrapping the filename within a span and setting a maximum width for the text. To ensure the scroll bar does not reappear, the bottom margin in the tabs-file-list class has been set to 0px.
Opening many tabs past the current width of the window also created an additional horizontal scroll bar for the body of the app. This issue has been mitigated by setting a width for the gz-editor class.
