added dropdown for suggestion of previous value of hashtags

[draunger]

description

added the dropdown functionality in the hashtags field so that it can show previous value of hashtags used..

approach:

• Extracted hashtags from recent changesets
• Formatted them for dropdown: removed '#' for storage but kept it for display
• Saved the original show function by using this => var origShow = hashtagField.show
• Enhanced it to set up dropdown when field becomes visible
• Preserved original behavior while adding new features
• Used uiCombobox to create the dropdown functionality
• Attached it to the input field when visible
• Shows recent hashtags as suggestions

I've pushed a commit to simplify the code a bit and make it more readable. Maybe you want to give it a look to check if it still works as intended @draunger?
