Tableview bug fixes and feature upgrades

[israel-dryer]

Lots of new exciting new features and minor bug fixes for the Tableview widget

Bug fixes

• entering a page less than 1 or greater than the max in the page entry no longer returns an empty or invalid page
• the +/- column options in the right-click menu now update when columns are deleted or inserted into the table
• Other miscellaneous not worthy of a write-up

New features

• Default stripe colors are added for all themes
• The stripecolor parameter is enhanced so that passing in a tuple with None for background and foreground colors will now cause that element to use a default color. For example: stripecolor=(None, None) will cause a default foreground and background color while stripecolor=('yellow', None) will cause a yellow background and default foreground color. The default setting of stripecolor=None will disabled stripecolors altogether.
• Bulk delete and insert is now available via the Tableview.purge_table_data and Tableview.build_table_data methods. Along with the existing insert methods, delete methods have been added for columns and rows to make the data handling full-featured.
