Color themes

It is now possible to change the theme. In addition to the default theme (called 'vista'), I have created a blue and a dark theme. If you think my color choices are poor or would like to request another theme, let me know :)
Theme can be configured under Options->General

I have also added the option to show the "Drops" tab below the "Timer" tab so you can see your current lap time and your drops in the same window. This should also be useful for streamers
This can be configured under Options->General

Fixed 3 bugs:

• Run times are now scrollable with the mouse wheel
• Fix bug occuring when setting a start run delay and clicking start new run repeatedly before the delay expired
• Fix a bug where using characters in your profile name which are not allowed for windows file names would result in a corrupt save file and config file
